Delta Introduces Two New Models for the Low Profile PMR Panel Mount Power Supply Series for LED Signage

Delta Electronics is extending the low profile PMR panel mount power supply series with two new models, PMR-5V320WDAA and PMR-4V320WCAA. The PMR series is designed for LED signage application where efficient heat dissipation for the components are crucial in a low profile control cabinet. At only 30mm height, the universal input products are made for installation in narrow space and are able to withstand polluted environment as the PCBAs are applied with conformal coating.

The PMR-5V320WDAA offers efficient thermal management without the need for fan and provides parallel connection option to increase the operational reliability of the connected LED signage. Whereas the PMR-4V320WCAA has built-in fan with automatic fan speed control that allows efficient thermal management and use of energy.

Major safety approvals include IEC/EN/UL 60950-1 for Information Technology Equipment (ITE); EMI standard according to EN 55022, Class B. The PMR series provides high power factor values and conform to harmonic current IEC/EN 61000-3-2, Class A and Class D. All Delta industrial power supplies are fully compliant with RoHS Directive 2011/65/EU for environmental protection.
