Compact size

High levels of efficiency obtained from our power supplies, have allowed to halve the size compared to a conventional power supply.

Manual Reset

To restart the output it is necessary to turn off the primary power supply for about 1 minute and then turn it back on. This mode is particularly recommended in applications where maintenance personnel are required. Just change the position of the Jumper!

Important Benefits

Unique product in stock adaptable to any input voltage and excellent for the management of any type of output current.

Semi-resonant Switching Technology: efficiency up to 93% and continuous and instantaneous output power.

Power Good – Output voltage control

The output voltage is continuously monitored, and the NO contact changes state every time the voltage drops below 20 Vdc. This application is used in redundant systems to ensure that power is always available to critical loads.

Hiccup Mode

In the event of a short circuit or overload, the output energy is interrupted.

The device retries every about 2 sec. to restore the output energy, cyclically, until the problem is solved. Just change the position of the Jumper!

Continuos Output Mode

In case of Short circuit or overload, the output current is kept maximum even when the voltage is at zero.This function is required to satisfy heavy loads such as motors, solenoids, lamps, PLCs with strong capacitive input loads and other devices that require strong current transients. Just change the position of the Jumper!

Output protected by magnetothermic switches

The output can be disconnected easily and safely. The defective part is disconnected, the defect is limited and the important parts of the system can continue to operate. Our power supplies generate 50% more energy as per EN60204 -1 which requires safe control in all overload and short-circuit conditions; the protections must intervene .

Power Boost

This feature allows to use small sizes of power supplies to cope with high current transients (Power Boost of 150%, for not less than 3 minutes) such as motors, solenoids, lamps. Otherwise it would be necessary to oversize the units.
