AC/DC converter module range suited to specialist applications

PowerPax has recently extended its range of 3W AC/DC module power supplies with the addition of the ultra-wide input LS03-16BxxSS and LD03-16Bxx series products from global power conversion manufacturer Mornsun. This range features an ultra-wide input range of 90VAC-528VAC (47-63Hz) and can accept a DC input of 100VDC-745VDC on the same terminals. The AC input range makes this product suitable for two wire connection to three phase four wire systems. The LS03-16BxxSS range features an input to output isolation of 4000VAC minimum and the LD03-16BxxSS series has an input to output isolation of 3000VAC minimum. Both ranges have an efficiency of up to 76% with maximum standby power consumption of 0.5W. These modules offer single DC outputs of 3.3V, 5V, 9V, 12V, 15V and 24V with a typical output voltage accuracy of ±5%, line regulation of ±1.5% typical and load regulation of typically ±2.5% (10% - 100% Load). Outputs have a low level of ripple and noise 180mV P – P Max (20Mhz Bandwidth) and all outputs feature short circuit protection (hiccup mode with continuous self-recovery) and over-current protection (self-recovery). Both product ranges are Class II and meet UL60950 and EN60950 standards and have excellent EMC characteristics. These converters have an operating temperature range of -40C to +85C and are designed for free air convection cooling. They are engineered for applications where reliability is key and they have an MTBF =300K Hr’s (MIL-HDBK-217F @ 25C) and a three year warranty. These units offer two different compact package styles with high power density. The LS03-16BxxS is provided in a DIP package with dimensions of 50.80mm x 25.40mm x 15.16mm and the LD03-16BxxS is a SIP package with dimensions of 44.50mm x 13.00mm x 24.00mm. This series of converters provide excellent performance whilst being cost competitive. They are particularly suited to applications including, but not limited to, three-phase electricity metering, industrial control and instrumentation, double power switch control and fire protection systems.
