REED RELAYS FOR HIGH POWER
Miniature, ultra-high packing density reed relays usually have a switching rating of up to 10 Watts and 0.5 amps, but some applications can require higher switching power and higher carry current specifications.
The Series 100HC and Series 114 offer 1A switching up to 40 Watts and 3A continuous carry current, the Series 144 offers 80W up to 2A and the Series 67 offers 3A switching up to 200W and 5A continuous carry current. Having the advantages of hermetically sealed contacts, fast operating speeds and very low leakage currents, these can offer an ideal solution over other switching technologies. In cold switching applications where current pulses are applied, up to 5 times the continuous carry current specification is achievable depending on the duty cycle.
Recommended Reed Relays for High Power
Series 144 – 80W High Power
2 A switching at up to 60 W, or 1 A switching up to 80 W, with a continuous carry current of up to 3 Amps. High-voltage capability, with a switching voltage of 1000VDC up to 10W and up to 3kV standoff. 1 or 2 Form A (energize to make) or 1 Form B (energize to break) configurations. 5 , 12 or 24 V coils.
Series 100HC – 3A Carry Current + High Coil Resistance
1 A switching at up to 40 W. High coil resistance of up to 6000 Ω for low power consumption. Form A (energise to make) or Form B (energise to break) configurations. 5 , 12 or 24 V coils.
The Pickering Series 100HC offers higher coil resistance than the similar specification Series 114, the greater winding space allowing for the use of switches rated to 3 Amps continuous carry current and even higher levels in pulsed current applications.
Series 114 – 40W High Power
1 A switching at up to 40 W, carrying 3 A. Form A (energize to make) or Form B (energize to break) configurations. 3, 5, 12 or 24 V coils. Suitable for high power applications and in many cases, may be used as an alternative to mercury wetted reed relays.
The Series 114 is a range of Single-In-Line reed relays intended for power levels that are beyond the capabilities of conventional dry SIL reed relays. The range features an internal mu-metal screen to minimize problems that would otherwise be experienced due to magnetic interaction when they are closely stacked.
Series 67 – 3A Switching at up to 200W
The highest power switch in the Pickering portfolio – Up to 200 W. 5, 12, and 24 V coils with optional internal diode. 1 Form A and 1 Form C configurations. Suitable for high voltage, electro solar and cable testing.
With a stand-off voltage of up to 8 kV, and capable of 6kV switching at 200W, Series 67 relays are constructed using a lead frame in a Single-in-Line (SIP) format and feature former-less coils which results in a smaller package than is usual for this type of device.
