ENA400M Series

Product catalog summary

Specifications

Input: Voltage and fuse requirements vary by model. Standby current is less than 1mA, and no load current is less than 30mA. Polarity protection is included, and over/under voltage shutdown is specified in the table.
Output: Voltage and current specifications are model-dependent. The device is short circuit proof with a constant current limit at approximately 110%. Over voltage protection is not available, but temperature protection with automatic recovery is included. Output ripple is 200 mV p-p at 25ºC, with line and load regulation at 2%.

Environmental Conditions

Operates in 100% relative humidity (non-condensing) and temperatures ranging from -20º to +50ºC. It is compliant with RoHS II and REACH standards.

General Features

Power efficiency is approximately 95%, with an IP67 rating. The device is cooled by convection and has a lifetime of 5 years at 25ºC with 80% load. MTBF is greater than 300,000 hours. Isolation is 500VDC between input/output and to the case. Dimensions are 150x93x31 mm, with an aluminium housing and polyurethane potting compound. Weight is approximately 850g.

Connections

Input and output connections are fixed 0.5m leads. Remote on/off is controlled by a fixed 0.5m lead (green), which connects to IN+ to enable output.

Standards

Immunity standards include EN61000-6-2;4-2;4-3;4-4;4-5;4-6, with a surge protection of 2kV. Emission standards are EN55022B (conducted and radiated). Safety standards are not applicable.

Model-Specific Information

Four models are listed with varying input voltage ranges, output voltages, and currents. External fuse requirements and voltage shutdown thresholds are specified for each model.
