CHAPTER 3 FPS1000 POWER SUPPLY INSTALLATION

3.1 GENERAL

This chapter contains instructions for initial inspection, preparation for use and repackaging forshipment.

NOTE

FPS1000 power supplies series generate magnetic field which might affect the operation of other instruments. If your equipment is susceptible to magnetic fields, do not position it adjacent to the FPS1000 unit.

3.2 PREPARATION FOR USE

In order to be operational the power supply must be connected to an appropriate AC source. The AC source voltage should be within the power supply specification. Do not apply power before reading sections 3.6 and 3.7. Table 3-1 below describes the basic setup procedure. Follow the instructions in Table 3-1 in the sequence given to prepare the power supply for use.

Table 3-1: Basic setup procedure

3.3 INITIAL INSPECTION

Prior to shipment this power supply was inspected and found free of mechanical or electrical defects. Upon unpacking of the power supply, inspect for any damage which may have occurred in transit. The inspection should confirm that there is no exterior damage to the power supply. Keep all packing material until the inspection has been completed. If damage is detected , file a claim with carrier immediately and notify the Lambda sales or service facility nearest you.

3.4 FPS1000 MOUNTING

The FPS1000 power supplies series is designed to fit in the FPS-S1U and FPS-T1U, 19" rack, or in an equivalent rack designed for the FPS1000 power supply. The FPS1000 is secured to the rack using the spring lock device, located at the FPS1000 front panel. Refer to the FPS1000 and the FPS-S1U and FPS-T1U outline drawings in Chapter 2, Chapter 11 and Chapter 18. When installation using mounting screws is required, the FPS1000 can be secured to the equipment using the M3 mounting holes at its bottom surface. Refer to the FPS1000 outline drawings.

3.5 LOCATION MOUNTING AND COOLING

This power supply is fan cooled. The air intake is at the front panel and the exhaust is at the rear panel. Upon installation allow cooling air to reach the front panel ventilation inlets and allow minimum 50mm of unrestricted air space at the rear of the unit for the air exhaust.

3.6 AC SOURCE REQUIREMENTS

The FPS1000 series can be operated from a nominal 100V to 240V, single phase, 47~63Hz. Refer to the specifications in chapter 1 for the input voltage range and the current required. Ensure that under heavy load, the AC voltage supplied to the power supply does not fall below the "low limit" specifications.

CAUTION

Connection of this power supply to an AC power source should be made by an electrician or other qualified personnel.

WARNING

There is a potential shock hazard if the power supply chassis and cover are not connected to an electrical safety ground via the safetyground in the AC input connector.

3.7 CONNECTING THE LOAD

WARNING

Turn off the AC input power before making or changing any rear panel connection. Ensure that all connections are securely tightened before applying power. There is a potential shock hazard when using a power supply with a rated output greater than 40V.

3.7.1 Load Wiring.

The following considerations should be made to select wiring for connecting the load to the power supply: * Current carrying capacity of the wire (refer to 3.7.2). *Insulation rating of the wire should be at least equivalent to the maximum output voltage of the power supply. *Maximum wire length and voltage drop (refer to 3.7.2). *Noise and impedance effects of the load wiring (refer to 3.7.3).

3.7.2 Current Carrying Capacity

Two factors should must be considered while selecting the wire size. 1.Wires should be at least heavy enough not to overheating while carrying the power supply load current at the rated load, or the current that would flow in the event the load wires were shorted, whichever is greater.

2.Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated current. Please refer to Tables 3-2 and 3-3 for maximum wire length to limit the voltage drop in American and European dimensions respectively.

FPS1000 Instruction Manual

3.7.3 Noise and Impedance Effects

To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted-pairs of the shortest possible length. Shielding of the sense leads may be necessary in high noise environments. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to reduce coupling between them, which might impact the stability of power supply. The sense leads should be separated from the power leads. Twisting the load wires reduces the parasitic inductance of the cable which could produce high frequency voltage spikes at the load and the output of power supply because of current variation in the load itself. The impedance introduced between the power supply output and the load could make the ripple and noise at the load worse than the noise at the power supply rear panel output. Additional filtering with bypass capacitors at the load terminals may be required to bypass the high frequency load current.

3.7.4 Inductive loads

To prevent damage to the power supply from inductive kickback, a diode should be connected across the output. The diode voltage and current rating should be greater than the power supply maximum output voltage and current rating. Connect the cathode to the positive output and the anode to the negative output. Where positive load transients such as back EMF from a motor may occur, connect a surge suppressor across the output to protect the power supply. The breakdown voltage rating of the suppressor must be approximately 10% higher than the maximum output voltage of the power supply.

3.7.5 Making the load connections

Hazardous voltages may exist at the outputs and the load connections when using a power supply with a rated output greater than 40V. To protect personnel against accidental contact with hazardous voltages, ensure that the load and it's connections has no accessible live parts. Ensure that the load wiring insulation rating is greater than or equal to the maximum output voltage of the power supply.

4.1 Input Voltage Range

Input voltage is single phase 85~265Vac (47~63Hz). The power supply can be operated also with a DC input voltage, 120~330VDC but the safety approvals apply to the AC voltage only. Input voltage which is out of the specifications might cause damage to the unit.

4.2 Output voltage trimming

The output voltage can be adjusted within the specifications via the V_Trim pin at the In/Out connector. Refer to Fig 4-1 typical connection and calculation of the adjustment resistors: Note that the Over Voltage Protection may trigger if the output voltage exceeds the maximum voltage specification.

4.3 Over Voltage Protection (OVP)

The OVP triggers when the output voltage exceeds the maximum rating and reaches the OVP limit. When the OVP is triggered, the output voltage shuts down. In order to resume operation, the AC input voltage should be removed for more than 30 sec. The OVP level is factory set and is not adjustable.

4.4 Over Current Protection (OCP)

A constant current limiting with automatic recovery is provided. The OCP operates when the output current exceeds 105%~125% of the rated output current. The output voltage recovers automatically when the overload condition is removed. Avoid operating the power supply under overload condition for long time as it might cause damage to the power supply.

4.5 Over Temperature Protection (OTP)

The OTP is activated when the ambient temperature or the power supply internal temperature exceeds a safe temperature. When the OTP is activated, the power supply output shuts down. The output recovers automatically when the ambient temperature or the internal temperature cools to a safe limit.

4.6 Auxiliary 12V output

An isolated 11.2V~12.5V output is provided (Referenced to the Signals_Return potential). The maximum output current from this output is 0.25A.

4.11 Remote Sensing

The Remote sensing compensates voltage drop on the load wiring. The maximum voltage drop on each wire is 1V, however, it is recommended to minimize the voltage drop on the load wires to improve the response to load current changes. In case that the sensing wires are long, use separate twisted pair wires for the sensing and for the load wires to minimize noise pick-up. It is recommended to connect electrolytic capacitors in the following locations:

1) Across the load terminals

2) Between the "+S" terminal and the "+V" terminal of the power supply.

3) Between the "-S" terminal and the "-V" terminal of the power supply.

Refer to Fig 4-6 for typical connection of remote sensing.

5.2 Connecting Single Load, Remote Sensing

Remote sensing is used in cases where the load regulation is important at the load terminals. Use twisted or shielded wires to minimize noise pick-up. If shielded wires are used, the shield should be connected to the ground at one point, either the power supply side or the load. The optimal point for the shield ground should be determined by experimentation. Refer to the power supply specifications for the maximum voltage drop allowed at the load wires.

5.3 Connecting Multiple loads, radial distribution method

In cases of multiple loads connected to one supply, each load should be connected to the power supply's output terminals using separate pairs of wires. It is recommended that each pair of wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation. The sense wires should be connected to the power supply output terminals or to the load with the most critical load regulation requirement.

5.4 Multiple loads connection with distribution terminals

If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by a pair of twisted or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig 5-4). If remote sensing is required, the sensing wires should be connected to the distribution terminals or at the most critical load.

5.5 Grounding outputs

Either the positive or negative output terminals can be grounded. To avoid noise problems caused by common-mode current flowing from the load to ground, it is recommended to ground the output terminal as close as possible to the power supply's output. Always use two wires to connect the load to the power supply regardless of how the system is grounded.
