Features
19” Rack Adaptable - 3U High Digital Output Metering 3 Digit DPM Constant Voltage / Constant Current Operation High Stability and Close Regulation ±0.01% Proven Reliability and Endurance 3U High Remote Sensing Facility for 5A & Above Rating Models

The New Series offers a range of Linear DC Regulated Power Supplies for use in Laboratories & Industries. Output voltage and current values are displayed on a 3 digit DPM.

These table top units are designed for 19” Rack Mounting.

There are fifteen models to choose from, with output power ranging from 30 watts to 300 watts. Output voltages of 0-16V, 0-32V, 0-64V and 0-128V DC are available for single output supplies. There are Six Dual output models with two independent isolated outputs. These outputs could be connected in series or parallel to double the voltage or current. A special model, LQ6324 with four independent outputs, has been designed for computer lab. All the models operate in either constant voltage or constant current mode and are fully protected against continuous output short circuit and overload.

DIGITAL LAB SUPPLIES are being sold all over the world since 1974 and several thousand units are currently in service.

OPTIONS AT EXTRA COST 1) 19” Rack mounting only for PS with 430mm width. 2) Over voltage protection. 3) Input 115V AC ±10%.
