Datasheet

UK power conversion distributor PowerPax has launched the Mornsun 5W LD05-23Bxx series of PCB mounting AC/DC switching power supplies that feature an Ultra-Wide range input accepting both AC and DC. This series has an input range of 85-305V AC (47-440Hz)/ 100 – 430V DC and features six models with outputs from 3.3V to 24V DC.

This range offers a high power density in a compact package (50.8 x 25.4 x 15.16mm) with efficiency of up to 83% and standby power consumption of 0.3 watts maximum.

Outputs require no minimum load and are well regulated with Line Regulation of ±0.5% and Load Regulation (10 – 100%) of ±1%.

Output voltage accuracy is ±3% typical for the 3.3V model and ±2% for all other outputs.

Output Ripple and Noise (20MHz bandwidth) is typically 60mV peak to peak for 3.3V & 5V outputs and typically 50mV peak to peak for all other output voltages.

All outputs feature continuous (self-recovering) short circuit protection, over current protection (self-recovering) and over voltage protection (shutdown).

This series meets UL60950, EN60950 and IEC60950 with Input to output isolation of 4000V AC (1 minute) minimum. They offer good EMC performance and high reliability, 300K hours (MIL-HDBK-217F@25°C).

The module is housed in a black flame-retardant and heat resistant plastic case that is UL94-V0 rated.

These modules feature an operating temperature range of -25℃ to +70℃, free air convection cooling (de-rating 2%/°C -25 to 0°C and 2%/°C +55 to 70°C). This series is suitable for a wide range of applications including electricity monitoring systems, LED control systems, instrumentation, telecommunications and civil applications.
