2.Technical Specifications

Input voltage range:

The power module can accept a wide range of external power supply voltages,usually 85~265VAC(another saying is 85~264VAC),and a frequency of 47~63Hz.

The nominal input voltage is 120VAC/240VAC.

Output capacity:

The rated output power is 75W.

It can operate stably in a wide temperature range(0~+60°C).

A variety of voltage and current output options are provided to meet the needs of different devices.

Other parameters:

The current capacity varies according to the output voltage,such as 4A at 3.3VDC,13A at 5.1VDC,and 2.8A at 24VDC.

With an isolation voltage of 250V(continuous)as rated.

Tested at 3500V DC for 60 seconds,with reinforced insulation and backplane power input.

III.Product Features

High efficiency and low energy consumption:

Adopting advanced technology and design,it has the characteristics of high efficiency and low energy consumption.

High reliability:

It can operate stably in harsh industrial environments,provide stable power supply,and ensure the normal operation of the entire system.

Good compatibility:

It has good compatibility with other products and systems of Rockwell Automation.

Compatible with various ControlLogix chassis,such as 1756-A4,1756-A7,1756-A10,1756-A13,1756-A17,etc.,especially B series and C series.

Power retention function:If the working input power is suddenly interrupted,this standard power supply provides a duration of 2 cycles at 85V AC,6 cycles at 60 Hz at 120V AC,and 20 cycles at 60 Hz at 220V AC.
