The Preen ADG-L-335-15 Programmable DC Power Supply provides users with a tool that is optimal for photovoltaic, electric vehicle, battery, fuse/capacitor and third party laboratory testing. This unit provides users with a tool that has high power density, low noise, and tight regulation. The combination of DSP and PWM technologies has enabled significant advances in stability and measurements. With CV/CC/CP modes and its high voltage and high power features, the ADG-L-335-15 is an ideal DC power for applications on photovoltaic (PV), electric vehicle (EV), battery charge simulation, fuse, and contactors. Users are provided with a tool that is capable of Parallel configuration for higher output levels. The ADG-L-335-15 is operated via the 5 in. intuitive touch screen or the rotary knob to quickly access measurements, setting parameters, and configurations. The Preen ADG-L-335-15 can also be controlled via standard RS-232, RS-485, Analog, Ethernet, USB and Analog remote interfaces, or through an optional GPIB interface (sold separately). The built-in simulation function allows devices to be tested on voltage dropouts, spikes and other repetitive testing for voltage and current.
