Important Safety Instructions

Before applying power to the system, verify that your product is configured properly for your particular application.

WARNIN

Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform installation and servicing.

Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis. Similarly, other power ground lines including those to application and maintenance equipment must be grounded properly for both personnel and equipment safety.

Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.

In normal operation, the operator does not have access to hazardous voltages within the chassis. However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO HUMAN SAFETY may be normally generated on the output terminals. The customer/use r must ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages is eliminated.

Guard against risks of electrical shock during open cover checks by not touching any portion of the electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses during open cover checks to avoid personal injury by any sudden component failure.

Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary sales organizations can accept any responsibility for personnel, material or inconsequential injury, loss or damage that results from improper use of the equipment and accessories.

SECTION 1

GENERAL DESCRIPTION

1.1 Introduction

The Sorensen DLM Series of 600W power supplies comprise a family of general purpose programmable supplies for rackmount and benchtop applications. The DLM 600W series consists of nine models, rated 5V/75A, 8V/75A, 10V/60A, 20V/30A, 40V/15A, 60V/10A, 80V/7.5A, 150V/4A, and 300V/2A.

A variety of user interfaces are available, ranging from manual front–panel control and standard non–isolated remote analog control, to optional GPIB or isolated remote analog control.

1.2 General Description

The DLM series power supplies incorporate the latest power conversion and control technology to provide high accuracy, excellent regulation, low output noise, and fast transient response. They utilize a switched–mode output power converter for high efficiency and power density. The converter has been optimized to provide performance approaching that of linear supplies. A high switching frequency combined with Zero–Voltage Transition power switching and dual–stage output filtering account for the excellent dynamic and noise characteristics. Precise regulation of output voltage or current is possible with operation as either a voltage source in constant–voltage mode (CV), or as current source in constant–current mode (CC). Crossover between modes is automatic, dependent on load demand.

The front panel contains all controls and indicators required for setting and monitoring the output parameters, as well as annunciation of operational status. Individual adjustment controls are provided for output voltage, current, and over voltage protection (OVP). Two 3.5 digit LED displays normally measure the output voltage and current. In conjunction with the preview switches, these displays also show the programmed values of voltage, current, or OVP. The preview functions allow adjustment of those parameters without disturbing load connections. LED indicators show the mode of operation (CV or CC), programming control source, or abnormal operating conditions. Switches are also provided to directly control the output power, and to switch between local and remote control.

M362161-01 Rev J 1-1

DLM 600W Series

The outputs are isolated from the chassis GND. However, an internal I0M bleeder resistor is connected from output return (-) to chassis ground. This allows operation with floating outputs, or with either the negative or positive terminal of the output referenced to chassis ground.

Master/slave paralleling is possible to allow multiple units to be operated in parallel for greater output current or power. The master unit has full control of the other slave units in setting the output voltage, current, and OVP. Multiple units can be connected in series for increased output voltage, within the 300V float limitation of the output terminals.

Remote programming is available with the standard non–isolated analog interface. Output voltage, current, and OVP are fully controlled with user selectable programming voltage levels or resistance programming.

Analog output signals are also provided to monitor the output voltage and current. In addition, a complement of digital input/output signals allows control and monitoring of the operational state of the supply. Optional interfaces such as GPIB, RS-232, isolated remote analog, and LXITM Class C Ethernet Interface allow adaptation of the supplies to a variety of applications.

AC Input Protection: internal fuses provided in each line of AC input for fault isolation Operating Temperature Range: 0C to 50C Storage Temperature Range: –40C to 65C Humidity: 90%, maximum non–condensing Altitude: 2,000m (6,562 ft) Transient Response: The output voltage will recover within 500 s to the steady–state

voltage level (within 0.1% of full scale) for a 50–100% or 100–50% load step change.

Efficiency: 84%, typical; 82%, typical for DLM 8–75; 75%, typical for DLM 5–75 Float Voltage: 300V(PK), maximum float voltage of either output terminal to chassis

ground

Display Type: 7–segment LED, 3.5 digits for voltage, current, and OVP Front Panel Adjustment Controls: Voltage and current controls are 10–turn precision

potentiometers. OVP control is 20–turn trimmer potentiometer. Overvoltage Protection (OVP): If the load voltage, at the point of sensing, exceeds

the OVP programmed value, the output converter will be shut down, and the output capacitors will be discharged with the downprogrammer. A secondary OVP monitor senses the voltage at the rear panel output terminals to protect against open sense leads. The unit can be restarted by cycling the AC POWER switch off and back on, cycling the OUTPUT switch, or by momentarily activating the remote shutdown.

Fault Shutdown: Supervisory circuits monitor for abnormal operation of internal circuits: overtemperature, logic supply fault, paralleling interface connection fault, cooling fan fault, output converter driver fault, output converter overcurrent fault. A fault condition will result in shutdown of the output converter, and the output capacitors will be discharged with the downprogrammer. The unit can be restarted by cycling the AC POWER switch off and back on, cycling the OUTPUT switch, or by momentarily activating the remote shutdown.

Parallel Operation: Up to four units of the same model can be connected in parallel. A master/slave paralleling interface is used for forced current sharing between the units. The master unit has programming control of the output voltage, current, or OVP. The current display of each unit shows its contribution to the total load current. The voltage display of the master unit shows the load voltage, while the voltage displays of the slave units are blanked out. A fault condition occurring within a unit will result in shutdown of all units. A paralleling interface cable is used to route control signals between the units.

Series Operation: Multiple units can be connected in series, limited by the 300V(PK), maximum float voltage of the output terminals of each unit to chassis ground. The output of each unit is set individually, and each unit displays its own output voltage and current.

1.4.4 Remote Analog Interface Characteristics Remote Voltage Programming: The output voltage, current and OVP can be

programmed from zero to full scale with an external voltage source with a user– selectable range of either 0–5 VDC or 0–10 VDC. The analog programming circuitry is not isolated from the output negative (return) terminal.

Remote Resistance Programming: The output voltage, current and OVP can be programmed from zero to full scale with an external resistance of 0–5 k. The analog programming circuitry is not isolated from the output negative (return) terminal.

Remote Resistance Programming Accuracy: Output Voltage = 1.5% of Vmax

Output Current = 2.5% of Imax OVP = 2.0% of 1.1  Vmax

Remote Monitors: Monitors for the output voltage and current provide a proportional analog signal with user selectable ranges of 0–5 VDC or 0–10 VDC, corresponding to zero to full scale of the output parameter.

Monitor Accuracy: Voltage Monitor, 5V Range = 0.5% of Vmax

Voltage Monitor, 10V Range = 0.75% of Vmax Current Monitor, 5/10V Ranges = 1.0% of Imax

SECTION 2

INSTALLATION

2.1 Introduction

The DLM Series power supply has been fully calibrated and tested prior to shipment; the unit is ready for immediate use upon receipt. However, when first unpacked, the unit should be inspected to ensure that no shipping damage has occurred.

2.2 Initial Inspection

Perform a visual inspection of the shipping container prior to accepting the package from the carrier. If damage to the shipping container is evident, a description of that damage should be noted on the carrier's receipt and signed by the carrier's driver.

Perform a visual inspection of the unit after it is removed from the shipping container. Check for shipping damage such as dents, scratches, distortion of the enclosure, or damaged controls. If external damage is evident, there may be internal damage as well. Immediately contact the carrier and file a claim for concealed damage. In addition, the shipping container and filler material should be saved for inspection. Forward a report of the damage to the Service Department where a customer service representative will provide instructions for repair or replacement of the unit.

2.3 Location Considerations

The power supplies are designed for rackmount and benchtop applications. As shipped, the supplies are configured for benchtop use. Conversion for rack mounting, simply requires removal of the four feet from the bottom of the chassis and adding the rackmount kit.

Since the units are fan–cooled, they require adequate clearance at the air intake and exhaust so that air flow is not impeded. The air intake is at the front and front sides, while the air exhaust is at the rear panel and rear sides. The temperature of the ambient air at the air intake should not exceed 50°C.
