High-power DC programmable power supply
Preen (AC Power Corp)
With more features, upgraded performance and all new local HMI design, the latest high-power DC programmable power supply, the ADG+ series, from Preen (AC Power Corp) has recently been unveiled. Claimed to offer great response time, high accuracy and many output voltage and current combinations, the ADG+ series is ideal for testing EV motor/compressor, DC/DC converter, server power supply, fuse/circuit breaker/contactor, and PV inverter or can be used as a facility power or EMC chamber power.
With output power up to 100kW per unit, the ADG+ series offers output voltage up to 2000V and output current up to 2500A in a single unit. Through easy master-slave parallel operation, the ADG+ output power can increase up to 300kW. Its remote sensing feature can effectively reduce voltage drop caused by cable length and provides more flexibility on installation.
Users can select standard RS-485, RS-232 and analogue interfaces or optional GPIB, Ethernet or USB interfaces. The advanced programmable features allow easy setup on test sequence and depending on CV/CC/CP settings and load conditions, ADG+ series can operate as a current or voltage source. The new I-V curve function can simulate the output characteristics of a solar array, and it is ideal for MPPT performance evaluation on PV inverters.
