Optimized for Cyclic High-Voltage Applications

Engineered for precision power management, the LQHDR 150kV/15kΩ/0.133A damping resistor delivers 265W of stable transient suppression. With its specialized cyclic operation profile (8 cycles/day max) and ultra-low partial discharge (LT 5pC), it's ideal for intermittent high-voltage systems requiring precise energy dissipation.

Cyclical Operation Protocol

Standard Operating Profile

Maximum 8 cycles per day with each cycle consisting of:

• 30 minutes: Full-load operation at 150kV/0.133A

• 60 minutes: Mandatory cooling period

Exceeding 8 cycles requires 12-hour system rest.

Thermal Monitoring

Infrared sensors should verify surface temperature ≤110°C during operation. Automatic shutdown required at 120°C.

Installation Guidelines

1. Maintain minimum 500mm clearance to grounded surfaces

2. Ensure ambient temperature ≤35°C (derate 3%/°C above)

3. Install vertical orientation with ±2° tolerance

4. Use corona rings for connections above 100kV

5. Verify creepage distance ≥35mm/kV (per IEC 60664-1)

Compliance & Safety

• Partial discharge: IEC 60270 compliant

• Impulse withstand: 250kV (1.2/50μs wave)

• Environmental rating: IP55 (dust/water protected)

• Safety margin: 180% rated voltage for 1 minute

• Flame resistance: UL94 V-0 certified housing
