Low-Profile and Fanless Power Supplies for LED Signage

Delta Electronics, Inc. has introduced the highly-reliable low profile PMR panel mount power supply series. The PMR series is designed for LED signage applications where efficient heat dissipation for the components is crucial in a low-profile control cabinet. The design offers highly-efficient thermal management without the need for fans. This increases the reliability of the product by reducing one moving part. At only 30mm height and encased in a full corrosion resistant aluminum body, the PMR-4V320WDAA which is the first model launched in the series also has built-in active PFC circuit.

Major safety approvals include IEC/EN/UL 60950-1 for Information Technology Equipment (ITE); EMI standard according to EN 55022, Class B. All Delta industrial power supplies are fully compliant with RoHS Directive 2011/65/EU for environmental protection.

Features of the PMR series include: Universal AC input voltage; Highly reliable fan-less design; Full corrosion resistant aluminum casing; Built-in active PFC and conforms to harmonic current IEC/EN 61000-3-2, Class A and Class D; Low profile design for 1U installation; and MTBF > 700,000 hours as per Telcordia SR-332.
