Glassman PS/EX040P035

The Glassman PS/EX040P035 is a high-voltage DC power supply delivering continuous, stable output across 0 to rated voltage and current. It combines adjustable voltage and current control with automatic crossover regulation to protect against overloads, arcs, and short circuits. The unit accepts single-phase AC input from 105–125 V RMS or 210–250 V RMS (48–420 Hz) and operates with input current below 1.5 A at full load (180 VA maximum). Output adjustment is available via external 0 to +10 V signal, external potentiometer, or case-mounted 10-turn potentiometer with 0.05% resolution. Voltage accuracy is 1% of rated plus 1% of setting, with repeatability better than 0.1% of full scale. The constant voltage/constant current architecture provides automatic mode selection based on load conditions. Stored energy remains below 400 millijoules in the 30 kV model. Current regulation holds better than 0.1% from short circuit to rated voltage across any set current value. The supply supports 0–100% programmable voltage and current as standard.
