Benefits at a glance

Save system costs

Reduced system costs

The PIC series is a future-proof and cost-effective investment for your system. The actual acquisition is only the beginning. With the PIC series you will permanently reduce your system costs. The high efficiencies (90.5 to 95.7% at full load) lower the heat losses and reduce your energy costs for the cooling of the system.

Process uptime

Increased process uptime

The high MTBF values (Mean Time Between Failures) of up to 1.72 million hours prove the absolute reliability of the PIC series. The power supplies are equipped with a DC-OK LED and they can also report the DC-OK signal via a floating relay contact (except PIC120.242C).

Flexible power supply choice

Flexible choice

The PIC portfolio allows you a high flexibility. The units differ in very subtle details which gives you the opportunity to choose only what you really need. For example: If you operate your systems exclusively in Europe or China you do not have to pay for a wide range input.

Mechanical robustness

Mechanical robustness

The clean board design and high-grade housing make the PIC series resistant to mechanical shock and vibration. The light-weight design of 350-810g also reduces the static strain on the DIN rail. All units also comply with the V0 class of inflammability.
