Product Details

NHDX series remote machine (alias: isolation converter or lower computer)

floor-standing

Pole type

1. Product Introduction:
The NHDX series remote unit is a load side voltage reduction and stabilization device that converts high-voltage direct current into stable direct current (DC/DC) or alternating current (DC/AC). It has high reliability, high power density, small size, light weight, strong heat dissipation and anti-interference ability, and is suitable for various installation environments.
2. Performance characteristics:
--Adopting SPWM/PWM power electronic conversion regulation technology;
--Equipped with lightning protection, overcurrent, overvoltage and overload protection functions;
--Both software and hardware adopt anti-interference design to improve anti-interference ability;
--Automatic power on function, no need to restart when receiving a call;
--Equipped with zero crossing start function when powered on;
--LED displays current and voltage;
--Equipped with remote control and communication interfaces for easy connection with computer control systems;
--All lines have undergone moisture-proof treatment, suitable for use in humid areas.
