Product Details

Description:

DS series high precision programmable DC power supply is our company launched in order to meet the needs of our customers a high quality, high power density, multi-functional cost-effective products, 3000W power density is only 1U size, voltage up to 2000V, current up to 200A, input voltage support AC and DC two modes, Ideal output for applications requiring a wide range of output voltage or current regulation, with constant voltage and constant current working modes. It can be used in automatic testing, process control, battery charging and aging testing where high quality DC stable power supply is required. This series of products have zero voltage "soft switch" function, which can effectively reduce switching transient stress, thus having very low output noise. The soft switch can also improve efficiency and reduce heat, thus making the power supply more stable.

Feature:

1.LCD display voltage, current, power

2.High performance, high power density, compact and light

3.Extended power/current/voltage in series and parallel

4.Built-in analog monitoring interface

5.Wide range of zero voltage current adjustment

6.Low ripple and noise, comparable to pure linear power supply

7.Voltage and current preset function

8.With remote measurement function

9.Multi-function keys and encoder combined operation, support List dynamic programming output, multi-data storage

10.Support automatic test function

11.Standard 485 communication interface, support Modbus standard communication protocol

3. Application areas

Electronic components test, aging; Battery, capacitor charging equipment; Motor and controller test; Aging of photovoltaic inverters and frequency converters; Precision electroplating, sewage treatment; Aging of LED and LCD screen; Laboratory, electronic equipment, automatic testing equipment; Electronic inspection equipment, production line equipment, communication equipment; Other places where high precision DC power output is required
