Preen's new ADG-L series is a programmable DC power supply with high power density, low noise, and tight regulation. The combination of DSP and PWM technologies has enabled significant advances in stability and measurements. The ADG-L series includes fourteen models with 4kW, 8kW and 12kW maximum output powers and several Auto Range models to provide a higher output current at lower output voltage. With CV/CC/CP modes and its high voltage and high power features, the ADG-L series is an ideal DC power for applications on photovoltaic (PV), electric vehicle (EV), battery charge simulation, fuse, and contactors. With a full 12kW in a 3U package it is designed for simulations in product development and automatic test system & integration. Parallel configuration is available to achieve higher output level. The ADG-L series is operated from the 5"intuitive touch screen or the rotary knob to quickly access measurements, setting parameters, and configurations. The DC power supply can also be controlled via RS-232, RS-485 and Analog standard remote interfaces or through optional Ethernet, USB, or GPIB interfaces. The built-in simulation function allows devices to be tested to voltage dropouts, spikes and other repetitive testing for voltage and current. This makes the ADG-L series ideal for various applications in renewable energy, EV, aerospace, DC/DC converter and electronic product markets
