800V DC Power Supply Systems for Precision Labs
Within high-voltage scientific labs, research facilities, and university engineering departments, choosing a high-precision laboratory 800V DC power supply is vital. High-voltage testing demands not just brute power, but absolute voltage stability, low electrical noise, and fast-acting hardware protections to safeguard sensitive test components and operators.
Ultra-Low Noise Ripple
Excessive electrical noise can distort semiconductor measurements and trigger false failures. AFB Power laboratory models keep ripple under ≤50mVrms / ≤120mVp-p, ensuring clean DC power for sensitive electronic circuits.
Galvanic Control Isolation
Standard USB, RS232, and LAN interface ports are fully isolated. This protects host PCs from high-voltage feedback spikes if a device under test fails or breaks down.
Dynamic Safety Interlocks
Includes external interlock loops (LOTO ready), automated discharge circuits that drain output terminals to safe levels (<42V) in under 2 seconds, and OVP/OCP safety thresholds.
DB9 Hardwired Safety Interlock Loop
The rear panel of every AFB Power unit incorporates a DB9 interlock terminal block. Laboratories connect this loop to physical door limit switches or emergency shut-off plunger buttons. If a technician 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.

Precision laboratory research requires stable output calibration. ETM laboratory power supplies leverage high-resolution 16-bit D/A and A/D converters. This enables a programming resolution of up to 12mV for voltage and 0.1mA for current limits, allowing researchers to sweep voltages with high repeatability.
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.
