PD-920 Arc Fault Sensor
The PD-920 Arc Fault Sensor delivers high-speed light detection for medium and high-voltage switchgear. Designed for critical safety, this unit uses advanced optics to minimize damage and ensure total system protection.
PD-920 Specifications
Detection
Utilizes dual point and radial fiber optic sensing modules with a sub-millisecond integrated trip response.
Operating Voltage
Universal power supply supporting a wide input range of 110V to 240V across both AC and DC current profiles.
Light Threshold
User-defined sensitivity parameters adjustable from 10klx to 100klx for precise LUX-based arc interference.
Output Relay
Features high-performance solid-state outputs or dry-contact electromechanical relays for ultra-fast tripping.
Data Logging
Integrated non-volatile memory registers that store comprehensive fault event data even during power loss.
Total Safety
Optical Detection
Utilizes a fiber optic lens to capture light intensity and trigger breaker trips in less than one millisecond.
Fast Response
Designed with a high-speed logic processor to detect arcs and mitigate catastrophic equipment explosions.
Easy Retrofit
The DIN-rail mounting platform allows for seamless integration or replacement of legacy protection relays.
EMI Shielding
Industrial-grade internal components ensure long-term stability in high-voltage electromagnetic environments.
