Crydom’s World Class Solid State Relay Technology is now available to Electromechanical Relay users in the industry standard 12 x 29 mm plug-in package with ratings of either 3 or 5 amps up to 280 VAC or 80 VDC.

Crydom’s new “LifePlus ED series” of AC and DC output pluggable Solid State Relays offer Electromechanical Relay users the opportunity to directly replace traditional 12 x 29 mm EMRs with Crydom’s proven Solid State Relay Technology. Solid State Relays offer substantial performance advantages over traditional EMR switching solutions in many applications including significantly greater life expectancy (>100 million operations), contactless high speed switching eliminating contact bounce and resulting electrical noise, precise logic compatible control inputs, acoustically silent operation and high vibration resistance, among many others.

Available in a SPST N.O. configuration, the “LifePlus ED series” offers output ratings of either 3 or 5 amps rms at 24 to 280 VAC, or 5 amps dc at 1 to 48 or 1 to 80 VDC, all at 40 °C ambient temperature. AC outputs incorporate Crydom’s proven Back-to-Back SCR technology while DC outputs utilize high efficiency FETs, both technologies resulting in the lowest possible on-state power dissipation and high surge current ratings which make the “Crydom LifePlus” an excellent choice for applications such as small Motors, Solenoids, Heaters and Lamps. Optically isolated control inputs available include 3 to 15 VDC, 18 to 32 VDC, 48 to 72 VDC, 18 to 36 VAC and 90 to 140 VAC.

Cydom’s “LifePlus ED series” relays are UL 508 recognized for both general purpose and motor control applications and compliant to IEC 62314 LC-A resistive and LC-B inductive application requirements. They are also CE certified to the IEC Low Voltage Directive and compliant to the IEC EMC Directive. The “LifePlus ED series” relays are available in the industry standard 12 x 29 mm plug-in relay package and fit standard DIN rail and PCB mountable sockets, allowing direct replacement of SPST N.O. EMRs in most applications. Featuring all solid state construction, “LifePlus ED series” SSRs provide an excellent improvement in performance over traditional EMRs .

Finder has introduced a pair of solid state relays for silent, high-speed switching of single and 3-phase loads rated at up to 5A.  The 77 Series relays’ 300A peak current handling capability makes them particularly suitable for use with high inrush current loads, including electronic starters and igniters for fluorescent and gas discharge lamps.

Two 77 Series relay variants are available:  ‘zero-crossover’, minimising voltage and current stresses to improve reliability and greatly reduce EMI, and ‘instant switching’, ensuring a consistent time between relay input and output, of importance where simultaneous switching is desirable as in 3-phase switching.

The relays have a single AC output and can be specified with either AC or AC/DC control inputs for added flexibility.  5kV insulation between input and output assures a high level of application safety and security.  Provided in a compact 17.5mm wide housing for 35mm rail mounting, the 77 Series also features an LED operational status indicator and an integral heat sink.

The solid state relay’s spark- and bounce-free switching characteristics ensure a virtually infinite electrical life, of particular benefit in high-speed, repetitive applications and in domestic and office environments, where electrical interference needs to be kept to the absolute minimum.
