TECHNICAL DATASHEET CliQ M DIN Rail Power Supply 24V 480W 1 Phase / DRM-24V480W1PN Highlights & Features Universal AC input voltage range Built-in active PFC with up to 94% efficiency Full power from -25C to +60C 5000m (16400 ft.) Power Boost of 150% up to 7 seconds Advanced Power Boost (APB) protect system and ensure continuing operation when large inrush current detected due to faulty load on a multiple load connection DNV GL and ABS approval for maritime applications DC OK Contact and LED indicator for DC OK/ Overload Conformal coating on PCBAs to protect against common dust and chemical pollutants Safety Standards CB Certified for worldwide use Model Number: DRM-24V480W1PN Unit Weight: 1.40 kg (3.09 lb) Dimensions (L x W x D): 124 x 82 x 127 mm (4.88 x 3.23 x 5.00 inch) General Description Delta Electronics is introducing one of the slimmest DIN rail industrial power supplies in its class, the CliQ M DIN rail power supply series. To fulfill the demands in maritime applications, the product is designed according to major industrial and maritime (Lloyds Register) safety standards. Other features include compliance with harmonic current IEC/EN 61000-3-2, class A, built-in DC OK contacts, and an LED for indicating DC OK and Overload conditions. In addition to having Power Boost of 150% up to 7 seconds, the CliQ M series is the first in the CliQ family to feature Advanced Power Boost (APB). With multiple loads connected in a system, a large inrush current could be drawn (demanded) due to one fault load. This will be detected by APB. The APB will trip the circuit breaker (circuit breaker with appropriate rating based on the system load) on the current path of the fault load due to high current. This thus prevents the system from shutting down while the other connected current paths continue to operate without interruption.
