ETP4890 Power System

ETP4890 is a power supply system using alternating current to direct current conversions for energy distribution. The small and modular ETP4890 power supply system supports easy installation and maintenance. The ETP4890 has an LCD interface that effectively facilitates management. The power supply system supports a maximum output current of 90 A.

Input terminals in the ETP4890 power supply system

The ETP4890 power system supports 220 V AC input.

Output terminals in the ETP4890 power supply system

The ETP4890 power supply system supports eight groups of output terminals each. The eight output terminals on the left are negative and the eight output terminals on the right are positive.

The ETP4890 power system supports the following functions:

• Transforms alternating current into direct current and provides direct current in communication devices.
• Communicates with the master device via the serial port COM or RS485 / RS232 sends control signals based on values of monitored parameters or a control command sent by the master device; detects power distribution parameters, PSU module parameters and additional digital parameters in real time.
• The system connects to one or two groups of lead-acid batteries using the monitoring module to manage batteries and accumulators.
• The system connects to the sensor's control box using the port DB50, detecting analogue and digital parameters and sending control signals.
• The device uses the monitoring module to monitor all operating parameters of the ETP4890 power supply system in real time, determine the operating status and report alarms at the appropriate time.
• The device clearly displays alarm monitoring information on the LCD display. The monitoring module allows to set parameters on the LCD display.
