Overview
DESCRIPTION
PMM0803 is a reliable and precise DC-DC converter with battery output.
It has two inputs which are 10-60v with 5V/4A output and 85-256VDC with 24V/5A output, all in the domain of two separate circuits to guarantee a continuous and unstoppable output outcome.
It features high efficiency; up to 88%, wide working temperature range -40~+85C and 3KVDC isolation voltage.
It uses an ATmega328 CPU along with an RS485 module for smooth communication along with any monitoring system.
PMM0803 follows a continuous-mode short circuit protection which comes with an over voltage and reverse polarity protection, it also contains a battery charging controller as well as BMS to protect the battery bank from overcharging and over-discharging.
This model has an added feature of a 0.95-inch OLED display that makes it easy and possible to monitor battery health and faults logs.
PMM0803’s power supply is excellent for the industrial environments with a harsh nature due to its high protection characteristics against high vibration, high dust, extremely low or high temperature.
