Sorensen DCS 50-20E Programmable DC Power Supply 50V 20A 1000W

Description

Sorensen DCS 50-20E Programmable DC Power Supply 50V 20A 1000W is ideally suited for a wide range of applications requiring DC power in a small form factor. Applications range from manufacturing test and burn-in of automotive components, avionics electronics, telecommunications and consumer products to beam steering, process control and laboratory R&D use.

The DCS Family of 1 kW, 1.2 kW and 3 kW programmable power supplies utilizes unique packaging techniques to achieve continuous full output power (1 kW, 1.2 kW or 3 kW) in any volt/amp combination within the rated output voltage and current limits in a low profile chassis, Demonstrated large installed base over a long period of time, the DCS family provides a highly reliable power platform.

This family has an easy-to-use front panel with 10-turn potentiometers to adjust voltage and current settings that are displayed simultaneously.  LEDs indicate overtemperature, remote programming, shutdown and over voltage protection, status and constant-voltage/current mode operation.  The DCS 3 kW Models have push button control of the output standby mode, OVP reset, remote/local programming and preview status of voltage, current and OVP setpoints.

The DCS family can also be controlled remotely.  Four analog control modes are standard as well as isolated analog control (option).  Computer control can be accomplished over IEEE488.2 GPIB (option) or LXI-compliant Ethernet (option).

Features

  • High power density / low ripple and noise
  • High programming resolution with Ethernet interface
  • Constant voltage and current mode
  • Remote sensing
  • Isolated analog control and monitoring (optional)

Specifications

Common
Meter Accuracy 1% of full scale + 1 count
Max. Voltage Differential from Output to Safety Ground 150 VDC
Remote Start/Stop and Interlock TTL compatible input or 12-250 VAC (12-130 VDC) or a contact closure
Cooling Internal fan, over temperature shutdown if internal heat sink exceeds set temperature
Remote Sense The maximum allowed sense line drop is 4V per line (2V on the DCS 8/10V 1 kW/1.2 kW models and 1V/line for all 3 kW models). Line drop subtracts from the maximum available output voltage at full rated power.
Remote Programming Enabled via external jumper on rear panel connector J3
Overvoltage Protection Crowbar type adjustable from 5-110% of rated output using front panel control (local or remote program selectable via J3 jumper)
Remote Analog Programming Linearity ±1% Accuracy: ±5%
