Ametek / Elgar 32V Mod. Master Power Module

The Ametek / Elgar 32V Mod. Master Power Module is a precision DC power supply component engineered for integration into AT8000A/B series modular mainframes. It delivers 32V DC at 6.25 A (200W output) with remote programmable voltage and current control, making it ideal for multi-channel test systems and industrial power applications requiring stable, configurable output. The master module supports master/slave operation—up to five slave modules can parallel with a single master to increase channel current capacity.
