BOP 1KW-GL POWER SUPPLY

This guide gives a brief introduction to the BOP 1KWGL Power supply, shows simple load connections, and allows you to verify the power supply is working. The guide also shows you how to perform the most commonly used functions.

ACCESSING MANUALS. First determine your Firmware Version (see below), then download the BOP 1KW-GL Operator’s Manual from www.kepcopower.com/support/opmanls.htm#bop-gl

Refer to the BOP 1KW-GL Operator’s Manual for full specifications, installation considerations and operating instructions. The BOP 1KW-GL Operator’s Manual also includes a full description of the digital interfaces and the SCPI command language.

FIRMWARE VERSION. With no load connected and power off, use either the GPIB port or RS 232 port (see page 6) to accept remote commands.

If necessary, refer to “Reset Power-up” on page 8 and Figure 5 to configure the GPIB address (default is 6) or configure the RS 232 baud rate (default is 9600).

Apply power to the unit and send *IDN? query. The unit responds with a character string containing the following fields: <Manufacturer>,<Model VoltageCurrent Calibration Date>,<Serial Number>, <Firmware Version> e.g., KEPCO, BOP1KW 20-50 09/30/ 2001,123456,4.01.

I — DESCRIPTION

The BOP 1KW-GL Series hereafter referred to as BOP-GL, are true 4-quadrant programmable voltage and current power supplies, meaning they are capable of both sourcing and sinking power (see Figure 1).

The BOP-GL models have been optimized for exceptionally low current ripple and noise and improved stability (drift and temperature), making them ideal for driving inductive loads such as large magnets or motors. These bipolar power supplies pass smoothly through zero without switching to provide true ± voltage and ± current. These BOP-GL power supplies use switch mode technology for low dissipation. A bi-directional, isolating, a-c input power factor correcting (PFC) circuit recuperates

energy sinked from an active load and sends it back into the line to maintain low dissipation.

These BOP power supplies can be controlled remotely by an analog ±10V input for the main channel (voltage or current), and by a +1 to +10V input for the limit channels. They can also be controlled through one of the standard digital interfaces (GPIB or RS 232) to set voltage and current and the four protection limits (+voltage, –voltage, +current and – current.) Output voltage and current can be remotely monitored via the analog monitor signals present at the rear panel Analog I/O Port connector, or by using SCPI commands via either the RS 232 or GPIB ports.

NOTE: When connecting active loads, the steady-state voltage of the active load must not exceed the maximum voltage rating of the BOP. Otherwise the overvoltage protection will shut down the power supply.

II — UNPACKING

This instrument has been thoroughly inspected and tested prior to packing and is ready for operation. After careful unpacking, inspect for shipping damage before attempting to operate. Perform the “Preliminary Operational Check” on page 5. If any indication

of damage is found, file an immediate claim with the responsible transport service.

VII — INSTALLATION

Install units either on a bench or in a 19 inch-wide rack. For rack mounting: first remove four feet; rack must provide support at the rear. Optional slides may be used. Leave the front and rear panels clear of obstructions to ensure adequate cooling.

INPUT CONNECTIONS. Source power is connected to the power supply via three-wire input power using the source power mating connector supplied (see Table 3). This power supply operates from single phase a-c mains power (or between two phases of 3-phase a-c mains power), 230V, 50/60Hz nominal (range: 176 - 264V, 47-63Hz) without any need for range selection. The user must provide a properly sized and rated mains lead (line cord) and service with a current rating compatible with the required input current. Line cords available as accessories are listed in Table 3. Plug the source power connector into the source power inlet connector at the rear panel.

LOAD CONNECTIONS.

! CAUTION:

Before connecting a load, verify that power up switch settings (see “Power-up Settings” on page 8) are compatible with your load.

Power connections require wires that are properly rated for the nominal output current of the unit. Connect the load to the OUTPUT and COMMON power terminals on the rear panel (see Figure 3). OUT S and COM S terminal of the Monitor and Sensing Terminal block are for connection of remote sensing leads (after removing the factory-installed local sensing links). NOTE: Output Sense lines must be connected for proper operation, either locally, or at the load (remote). Also use OUT S and COM S to monitor voltage at the load using external equipment such as a DVM, oscilloscope, etc. Use OUT
