TDK 750W HALF RACK Multiple output power system, Control via the serial communication port

Page 15

∗Parallel operation (Master/Slave) with Active current sharing.

∗Remote sensing to compensate for voltage drop of power leads.

∗External Analog Programming and Monitoring standard (0-5V or 0-10V, user selectable).

∗Cooling fan speed control for low noise and extended fan life.

∗Zero stacking-no ventilation holes at the top and bottom surface of the power supply.

∗Optional GPIB interface (SCPI compatible).

∗Optional Isolated Analog programming/monitoring (0-5V or 0-10V, user selectable and 4- 20mA).

1.2.4Multiple output power system

The GenesysTM power supplies series can be configured into a programmable power system of up to 31 units using the built-in RS232/RS485 communication port and the RS485 linking cable provided with each power supply.

In a GPIB system, each power supply can be controlled using the optional GPIB controller (fac- tory installed).

1.2.5Control via the serial communication port

The following parameters can be programmed / monitored via the serial communication port:

1.Output Voltage setting.

2.Output Current setting.

3.Output Voltage measurement.

4.Output On/Off control.

5.Output Current measurement.

6.Foldback protection setting

7.Over-voltage protection setting and readback.

8.Under-Voltage limit setting and readback.

9.Power-supply start up mode (Auto-restart or Safe-start mode).

1.2.6Analog voltage programming and monitoring

Analog inputs and outputs are provided at the rear panel for analog control of the power supply. The Output Voltage and the Current can be programmed by analog voltage or by resistor, and can be monitored by analog voltage. The power supply output can be remotely set to On or Off and analog signals monitor the proper operation of the power supply and the mode of operation (CV/CC).

1.2.7Parallel operation

GenesysTM power supplies of the same Output Voltage and Current rating can be paralleled in a master-slave configuration with automatic current sharing to increase power available.

1.2.8Output connections

Output connections are made to rear panel bus-bars for models up to 60V and to a 4-terminal wire clamp connector for models above 60V rated output voltage. Either the positive or negative terminal may be grounded or the output may be floated. Models up to 60VDC Rated Output shall not float outputs more than +/- 60VDC above/below chassis ground. Models >60VDC Rated Out- put shall not float outputs more than +/-600VDC above/below chassis ground. Contact factory for assistance with higher float voltage applications.

Local or remote sense may be used. In remote sense, the voltage drop on the load wires should be minimized. Refer to the specifications for the maximum voltage drop value.
