Teledyne Relays has added a range of Power DC Solid State Relays with load voltage ratings from 42V to 1700V, with load currents ranging from 5A to 150A to its Solid-State Power Relays catalogue.

Relays with ratings up to 10A are packaged in printed circuit mountings, with all other devices being chassis mounted. Each relay incorporates the latest IGBT or MOSFET switching technology which gives ultra low on-state resistance keeping power dissipation and off-state losses to a minimum. Innovative new control circuit designs minimise control current consumption and provide fast switching to keep power transients low.

The chassis mounting relays are designed to operate continuously, using the correct heat sink in the ambient temperature range of -40 to +90°C or -25 to +90°C. The PCB mounting relays operate continuously in an ambient temperature range of -40 to +80°C or -20 to + 80°C using a heat sink where specified. Data sheets on the DC Power range of solid state relays are available from www.teledyne-europe.com where you will also find information and data on all Teledyne switching products.
