DC Surge Protection Device for PV System
BKPD-B80-4P
Frequency: 50Hz/60Hz
Voltage: 220V/380V/420V
Function: It can be used as the building’s low-voltage main distribution cabinet, outdoor distribution control cabinet and lightning strike (overvoltage) protection.
Purpose: Low-voltage main distribution cabinets of various buildings, outdoor power distribution control, and power supply level one lightning protection systems with high risk of lightning strikes.
1. Product Overview
BKPD type power supply surge protector is suitable for various low-voltage distribution systems with grid voltage below 1000V and frequency 50/60Hz, such as post and telecommunications, railways, computer networks, electric power, meteorology, transportation, petroleum, coal, oil fields, Lightning protection and operating over-voltage protection for electronic and power equipment in the chemical industry and other fields. Protect the electrical appliances (such as control equipment, instruments and equipment, various electrical appliances, etc.) of these power-consuming units from damage caused by lightning strikes, transient overvoltages and other surge overvoltages. Ensure equipment and personal safety. It is an ideal overvoltage protection device.
