A2800 series
PROGRAMMABLE HIGH POWER DC-POWER SUPPLIES
 |
These high efficient switch mode power supplies - called A2800 - series - are designed to fulfill all the requirements of industrial, research and development application. A large number of standard models with output ratings from 7.5VDC-300A to 600VDC-4A are available from stock. The units are small, lightweight and inexpansive - they are all designed for maximum power. The programmability of the A2800 can be made either analog(0-5/10VDC) or with an optional build in GPIB/ IEEE488 or RS232- interface.This changes the A2800 into a computer programmable power supply. Automatic crossover CV/CC, thermal shutdown, sense, standby, 10-turn-pot's and 3-digit LED's for voltage and current are standard features.
Approvals: CE / LVD, UL, CSA.
