MK-TX Series of high frequency switching communication power

Overview

MK-TX is a high frequency switching communication power supply system design for the telecommunications, wireless base station. It use advanced phase-shift PWM high-frequency resonance technique, with the advantage of stable voltage, fast dynamic response, low output noise, good anti-interference ability, wide operation temperature range and so on.

Features:

MK-TX is composed of high frequency switching rectifier modules, monitoring modules, AC power distribution unit, DC power distribution unit and a cabinet.

The available rectifier capacity for 48V Series: 48V 10A, 48V 25A, 48V 30A, 48V 50A, 48V 100A and 24V Series: 24V 20A, 24V 50A, 24V 75A. System capacity can reach 100A～3000A. Current are automatically balanced among modules. Modules can be replaced online. System capacity is easy to expand.

Rectifier modules use advanced high-frequency resonant phase shift PWM technology, greatly improving efficiency. Monitor module can manage the power systems and battery intelligently, and can achieve centralized monitoring through Public or private telephone line.

Working status, voltage and current is displayed clearly and intuitivly on the panel. And it provides various protection such as automatic fault monitoring, fault alarming. MKtx has built-in floating\equalizing charging conversion, which could be changed either manually or automatically. Equipped with RS485 interface to communicate with control room.
