FAQ

Surge protectors are categorized into power and signal types. Power SPDs use core components like metal oxide varistors (MOVs) or graphite gaps, while signal SPDs rely on gas discharge tubes (GDTs) or transient voltage suppressors (TVS). In general, when a surge exceeds a predefined voltage threshold, the SPD diverts the surge energy to the ground. Under normal operating conditions, SPDs remain inactive and do not interfere with equipment performance.

• Power SPDs: Typically have an indicator window: green for normal, red for failure. They also include a remote alarm contact for integration into monitoring platforms.

• Signal SPDs: Currently lack direct failure detection methods. If signal transmission is interrupted, inspect the SPD for failure.

In all cases, replace failed SPDs immediately to prevent equipment damage from subsequent lightning strikes. Regular maintenance is critical.

Common causes for power SPD failures include:

• End of lifespan: SPDs degrade over 5–10 years due to minor leakage currents. Aging increases burnout risk.

• Overvoltage: Exceeding the SPD’s maximum continuous operating voltage (Uc) causes short-circuiting. Select SPDs with sufficient voltage margins based on regional power standards.

• Internal defects: Poor insulation or unstable resistance values.

• Human error: Incorrect installation, maintenance, or misuse.

Yes. Our products are rated IP55+ and operate reliably in extreme temperatures (-40°C to 85°C), making them ideal for factories, data centers, and outdoor infrastructure.  

Key differences:

1. High power capacity: PDUs start at 2.5kW, with KILOAMP models exceeding 20kW.

2. Global socket standards: Support IEC, NEMA, BS, and 20+ others.

3. Modular customization: Sockets and functional modules (e.g., surge protection, smart monitoring) are configurable.

4. Advanced features: Overload/voltage protection, DCIM integration, and remote management. Standard outlets lack these capabilities and are unsuitable for rack-level power distribution.

Basic PDUs provide simple power distribution. Smart PDUs add remote monitoring, load balancing, environmental sensing (temperature/humidity), and DCIM integration to reduce manual oversight.

PDU input currents typically range from 10A to 63A. Common copper cable specifications are as follows:
