KDY-20-D12(8/20µs)

KDY-20-D12 type 2 DC surge arresters/SPD is designed to protect DC load current, installs at or within equipment such as DC servo mechanisms, fire alarm monitoring systems, security system controls, telecom and datacom systems, microwave communication system, etc. to provide compact, heavy duty surge suppression. It utilizes high energy metal oxide varistors/MOV, providing a protection in CM/DM(L-PE,N-PE, L-N). These SPD are DIN rail compatible and is connected in parallel on the line to be protected.

 

Main Features

• Type 2 surge protector for DC power system
• Imax - 20kA/pole (8/20 waveform)
• Un – 12Vdc
• Up – 500V @ In
• Fast clamp response, under 25ns
• No leakage, no operating currents
• High energy anti-surge components MOV
• State-of-the-art surge protection technology
• Failure status indicator, green/red
• Telesignailsation indicator for remote failure alerts (optional)
• DIN rail mounting, pluggable module, convenient replacement

 *Installation Notes

1. Installation must be performed only by electrically skilled operator.
2. Disconnect power before installing, no hot-line operation is allowed, and better to under the guidance of professional electrician.
3. For best performance, mount protector in parallel with the equipment it is protecting as close as possible. (*Note: If protector is to be located outdoors and exposed to elements, mount protector inside a suitable weatherproof enclosure.)
4. Use a circuit breaker in series with the protector.(*Note: if a breaker is not available, use a fused disconnect switch or a fuse block. Fuses should be time-delay type.)
5. Green tab, normal work status, Red tab, failure status, need to be replaced rapidly.
