The Powerbox OFM1005127 is a 100W single output AC/DC switch mode power supply designed for medical and commercial ITE applications. It features an open frame construction with a standard 2x4 inch footprint (51 x 102 x 32 mm).
This power supply operates with a universal input voltage range of 90-264VAC and provides a fixed 18V output with 5% tolerance. It offers high power density and superior EMC performance, with features like intelligent over-temperature protection and over-voltage protection. The efficiency is rated between 87-90% at 230VAC full load.
Designed for reliability, the OFM1005127 meets safety standards including IEC/UL 60601-1 and IEC 60950-1. It has Class I isolation and a leakage current of less than 75µA. The operating temperature range is 0°C to 50°C, with derating applied at higher temperatures or with convection cooling.
Key electrical specifications include a maximum input current of 2A, an inrush current of 50A peak, and a hold-up time of 35ms at 230VAC. Overcurrent protection is approximately 125% with auto-recovery. The unit is RoHS, REACH, and WEEE compliant.
Nominal input voltage is 100-240VAC; operating range is 90-264VAC.
Output voltage is 18V nominal with 5% tolerance; continuous output power is up to 100W.
Operating temperature is 0°C to 50°C according to IEC60601-1, and 0°C to 40°C according to IEC60950-1.
The converter is chassis mount in an open frame package.
Overcurrent protection at approximately 125% with auto recovery, overvoltage protection, and overtemperature protection with auto recovery and output power limiting.
Dimensions are 51mm (length) x 102mm (width) x 32mm (height); maximum weight is 200g.
Approved according to IEC60601-1 Edition 3.1 and IEC60950-1.
