Preen ADG-L Series FAQ

1. What makes the ADG-L Series a strong choice for low-voltage, high-current testing?
   The ADG-L Series combines high power density, tight regulation, and low ripple performance to support demanding low-voltage, high-current applications with confidence. With models designed for protection component testing, AI server power modules, and other precision workloads, it delivers the stability and control needed for repeatable results.
2. Can the ADG-L Series be used in automated test systems?
   Yes. The ADG-L Series is equipped for easy integration into automated environments with standard RS-232, RS-485, Ethernet, USB, and Analog interfaces, plus optional GPIB for expanded connectivity. Remote programming, sequence control, and master/slave parallel operation help streamline setup and improve workflow efficiency.
3. Does the ADG-L Series support simulation and dynamic DC testing?
   Yes. Built-in programming and simulation functions make it easy to create dynamic voltage and current profiles, including sag, pulse, dropout, spike, rise, and fall events. This allows users to evaluate device behavior under changing conditions without relying on complex external programming.
4. Can the ADG-L Series be used in parallel and how many units are required?
   Yes, the ADG‑L Series supports parallel operation, allowing multiple units to be connected to increase total output power. Up to five units can be paralleled in a master/slave configuration, where one unit acts as the master and controls up to four slave units, automatically distributing settings and ensuring proper current sharing. This setup enables the system to scale up to as much as 75 kW of total output power using five 15 kW units.
