800V DC Power Supplies for High Voltage Laboratories
Scientific R&D cells, university electrical engineering classrooms, and national aerospace testing beds require a precise 800V laboratory DC power supply with rigorous safety precautions. Traditional high-voltage sources lack proper user barriers. eTommens power supplies deploy galvanic hardware safety interlocks, remote sensings, and under-75mV residual voltage ripplings specifically customized for precision research environments.
16-Bit Resolution DACs
Allows precision tuning increments of 12mV. Critical for tracing material dielectric breakdown curves.
Ultra Stable Compensation
Maintains exact selected voltage thresholds with drift deviations under ±0.01% of full scale over 8 hours.
DB9 Rear Panel Interlock
A physical contact switch loop. If safety doors or enclosure domes are opened, the unit shuts off instantly.
Active Capacitor Bleeder
Safety discharge circuitry actively bleeds hazardous high-voltage residual levels down below 40V in under 2 seconds.
DB9 Hardwired Safety Interlock Loop
The rear panel of every eTommens unit incorporates a DB9 interlock terminal block. Laboratories connect this loop to physical door limit switches or emergency shut-off plunger buttons. If a student or worker enters the high-voltage test area, the physical contact path opens, triggering an absolute mechanical-level solid-state shutdown of the high-voltage IGBT inverter stage, independent of microprocessor commands.
Hardwired safety interlock circuit closed. Output is permitted to activate.
Technical Standards & Regulatory Citations
Laboratory high-voltage electrical setups must satisfy strict safety requirements for testing personnel. Compliance with the international standard IEC 61010-1 Safety Requirements is essential to ensure measurement and control equipment used in laboratories prevents shock hazards under normal and single-fault conditions.
For academic research cells and semiconductor testing requiring low ripple limits, refer to the official eTM-8001 Low-Noise Precision Model Specs. It delivers a 1A rated output with low drift deviations and a precise 12mV tuning resolution.
