Description

IRM-20 is a 20W miniature (52.427.224mm) AC-DC module-type power supply, ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipment. This product allows the universal input voltage range of 85~305VAC. The 94V-0 flame retardant plastic case potted with silicone enhances heat dissipation and meets the anti- vibration demand up to 2G; moreover, it provides fundamental resistance to dust and moisture. With a high efficiency up to 85% and extremely low no-load power consumption below 0.1W, the IRM-20 series fulfils the worldwide regulation for the low power consumption requirement for electronics. The entire series is a Class Il design (no FG pin), incorporating the built-in EMI filtering components, enabling compliance with BS EN/EN55032 Class B; the supreme EMC features to keep the end electronic units from electromagnetic interference.

OTHERS

| MTBF| 10656.2K hrs min.      Telcordia SR-332 (Bellcore) ; 970.3K hrs min.      MIL-HDBK-217F (25℃)
DIMENSION| 52.427.224mm (LWH)
PACKING| 0.05Kg/240pcs/13Kg/0.94CUFT
NOTE| 1.  All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.

2.  Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3.  Tolerance :includes set up tolerance, line regulation and load regulation.

4.  The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitudes higher than 2000m(6500ft).

5.  The power supply is considered as an independent unit,but the final equipment still needs to confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”
