OFPS- Series
Introducing Essen’s OFPS Series: Cost-effective AC-DC switch mode power supplies engineered for streamlined industry automation. With a universal input range (90-270VAC, 50-60Hz), these power supplies are designed without a cover for seamless integration within larger enclosed systems. These compact SMPS units boast ultra-low no-load power consumption (<0.5W, Green Power) while ensuring stringent protections against short circuits, overloads, over-temperature, and overvoltage. Select from industry-standard 5V, 12V, or 24V DC output voltages across all power ratings, providing extensive options for OEM customers seeking optimal solutions.
- Universal input Voltage Range [ 90-270 VAC/120V-360VDC] in all models
- Load Regulation – Within 1% of output from 0% to 100 % rated load.
Characteristics
The OFPS series of ACDC Switch Mode Power Supplies (SMPS) from Essenare intended for low cost automation needs of industry. These universal input (90-270VAC, 50-60 Hz)
power supplies have no cover and are meant for use inside a bigger enclosed system. These miniature
SMPS feature extremely low no-load power consumption (<0.5W, Green power) which is a strict
requirement for European, American and other developed markets. The OFPS series has complete
protections such as short circuit, overload, over-temperature and over voltage. Industry standard output
voltages 5V or 12V or 24V DC, are available for all power ratings thus offering a large selection
range to the OEM customer.
