Descripción

The ETP4890-A2 is an efficient telecom power supply equipped with 3 R4830N rectifiers, each providing 30 A of current. The total output current of the device is 90 A, which at 53.5 V DC results in approximately 4800 W of power. The output voltage range is -42 ~ -58 V DC (with a default value of -53.5 V), while the input voltage range is 85 - 300 V AC (at 45 ~ 66 Hz). The maximum number of connected loads is 4.

Included with the unit is the SMU01B controller, which features 7 digital and 2 analog inputs, as well as 8 alarm connectors. Additionally, it has a fast Ethernet port and RS232/485 ports for communication.
