NSPV surge protective device DC SPD protect against lightning surge voltages in solar system (photovoltaic power supply system). These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.High energy MOVs equipped with specific thermal disconnectors and related failure indicators.

NSPV surge protective device AC Surge protection device(SPD) is an indispensable device for lightning protection of electronic equipment. It is used to limit the instantaneous overvoltage of the power line and signal transmission line to the voltage range that the equipment or system can withstand, or A powerful lightning current drains into the ground to protect the protected equipment or system from impact and damage.

NSPV MCCB DC The moulded case circuit breaker has the protection devices of over load, short circuit and under voltage, it can protect the circuit and power equipment from broken. The MCCB has the features of small volume, high breaking capacity, short electric arcing and anti-vibration. It is the ideal product for application in land and ship.

CT-5321 Modbus Serial Port Module 1 Module Description The Modbus serial port module supports 1 channel RS485/RS232 /RS422 (optional), supports Modbus RTU/ASCII protocol, and supports master, slave and free transparent transmission mode. The serial Module CT-5321 could be applied with the adapter modules, so it could convert Modbus into other protocols such as Modbus TCP, Profinet, EtherCAT, EtherNet/IP, etc. When the module is used, serial port parameters and Modbus instructions should be configured in IO Config software. Devices with RS485/RS232/RS422 interface, which support modbus-RTU /ASCII, could be applied with CT-5321 to realize interconnection with upper PLC or upper computers. CT-5321 could be applied with devices such as: PLC, DCS, remote IO, VFD, motor start protection device, intelligent high and low voltage electrical apparatus, power measurement device, intelligent field measurement equipment and instruments, etc.
