20KA OMP-ASA20/220-EO AC220V AC120V DC48V AC/DC24V DC12V Terminal Equipment AC/DC Surge Arresters,T2/T3 Class II/III D Experimental Test Level
Description:
OMRDON OMP-ASA20 series composite power supply lightning protector (SPD/surge arrester) is used for lightning protection of AC/DC powered terminal equipment.
Because the lightning strike electromagnetic pulse induction or surge, etc. will produce a strong overvoltage and overcurrent, invasion of the power supply line after the damage to the equipment. This product can withstand 20KA (8/20μs) lightning current impact, the use of two-stage composite balanced safety circuit, differential mode (X-X), common mode (X-PG) full-mode protection, common-mode protection; and X-X, X-PG between the leakage current-free design, compared with similar products can effectively extend the life of the protector, to protect the normal operation of equipment.
This product is often used in PLC industrial control system, security monitoring cameras, base station terminal communication equipment, switches, background broadcasting system, fire system power supply, household appliances and so on.
The product adopts aluminum alloy anodized shell, beautiful appearance, E-type terminals, solid wiring, cable will not fall off. With LED failure indicator, clearly understand the working status of the protector, simple maintenance. Industrial-grade design, can work stably for a long time in a harsh environment.
Functional Features:
- The maximum through-current capacity: 20KA (8/20μs), the use of two-stage composite balance of the safest circuit, the zero line and the firewire is connected to the rear lightning protection circuit, differential mode (line to line), common mode (line to ground) full-mode protection, residual voltage is low, especially suitable for outdoor equipment, by the lightning energy, the residual voltage value of the requirements of the more stringent installation sites.
- No leakage current, more stable performance, longer service life;
- With two levels of current drain, filtering, clamping, so that overvoltage, overcurrent can be effectively suppressed;
- With LED lightning failure indicator, normal (green) / failure (off).
Typical applications:
- PLC industrial control system.
- Security Monitoring Camera.
- Base station terminal communication equipment.
- Switchboards.
- Background broadcasting system.
- Fire Fighting System Power Supply.
- LED Lighting Street Lamp.
- Household appliances.
