Primary-switched TRIO POWER power supply with push-in connection for DIN rail mounting, input: 1-phase, output: 24 V DC/5 A 

## Product Description 

TRIO POWER power supplies for more stringent EMC requirements in shipbuilding 

The TRIO POWER power supply range with Push-in connection has been perfected for use in shipbuilding. All functions and the space-saving design of the single and three-phase modules are optimally tailored to the stringent requirements. Under challenging ambient conditions, the power supply units, which feature an extremely robust electrical and mechanical design, ensure the reliable supply of all loads. 

## Your advantages 

Can be used on the bridge of a ship in accordance with EN 60945 

- Increase system availability, thanks to dynamic boost with 150% of the nominal current for five seconds 

- Maximum flexibility due to the wide temperature range from -25°C to +70°C and device startup at -40°C 

- Electrically robust, thanks to high electric strength 

- Mechanically robust, thanks to high vibration and shock resistance 

Save time and costs, thanks to the Push-in connection and narrow design
