Compact Size

The high efficiency levels of our power supplies have allowed us to reduce their size by half compared to traditional power supplies, ensuring a more compact design without compromising performance.

Manual Reset

To restart the output, this mode requires interrupting the primary power supply for about 1 minute and then manually turning it back on. It is especially useful in applications where personnel safety is a priority, as it prevents automatic restart after a fault, forcing a conscious and controlled intervention. To enable this function, simply change the jumper position.

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 – Continuous Output Voltage Monitoring

The output voltage is continuously monitored. A normally open (NO) contact changes state whenever the voltage drops below 20 Vdc.

This “Power Good” signal allows timely detection of voltage drops that could compromise the operation of powered devices.

This function is particularly useful in redundant systems, where continuous monitoring of power supplies is essential to ensure operational continuity and safety.

Hiccup Mode

In case of a short circuit or overload, the power supply cuts off the output power.

The device automatically attempts to restore the output voltage approximately every 2 seconds, repeating the cycle until the issue is resolved.

This mode can be easily enabled or disabled by simply changing the jumper position.

Continuous Output Mode

In the event of a short circuit or overload, the output current is maintained at maximum even when the voltage drops to zero. This function is essential for heavy loads such as motors, solenoids, lamps, PLCs with high capacitive input loads, and other devices requiring strong current transients. Simply change the jumper position to activate it!

This allows the power supply to support current peaks without interrupting the output, preventing malfunctions or unexpected shutdowns.

Output Protected by Circuit Breakers

The output can be easily and safely isolated via circuit breakers. In case of a fault, the defective part is quickly disconnected, limiting the issue and allowing the critical parts of the system to continue operating without interruption.

Our power supplies deliver 50% extra power, in accordance with EN 60204-1, which requires secure control under all overload and short-circuit conditions, ensuring timely activation of protections.

Power Boost

This feature allows the use of smaller power supplies to handle high current peaks (Power Boost up to 150% of nominal power for at least 3 minutes), typical of loads such as motors, solenoids, and lamps. Without this function, the power supply would need to be oversized to manage such transients.
