HIGH VOLTAGE 4KV REED RELAY

High Voltage SIL / SIP Reed Relays - For up to 4 kilovolts

Pickering’s new and improved Series 104 high voltage isolation reed relays. These relays can now stand-off up to 4kV, switching at up to 25W. There is also an option for an electrostatic shield between the switch and the coil to help minimise noise between the coil drive and high voltage circuits.

Series 104 reed relays are suitable for many applications including mixed signal semiconductor testers, high-end cable testers, backplane testers, medical electronics, electric vehicles, solar energy and high voltage instrumentation.

104HT specifically designed to endure high temperature environments of up to 125°C, whilst capable of standing off up to 4kV DC. For those requiring even greater resilience, there is an optional extra available during the manufacturing process to enable the 104HT to endure temperatures as high as 150°C.

The Series 104 is a range of Single-In-Line reed relays intended for voltages that are beyond the capabilities of conventional SIL reed relays.

They are suitable for many high voltage applications such as transformer or cable testing, mixed signal testing, electric vehicles, solar energy, medical equipment, mining and mass spectrometry or any other automatic test equipment where high voltages are involved.

Where mains voltages are switched, for example to control and isolate S.C.R. or triac gates, these reed relays are an ideal choice.

One or two Form A (energize to make) or one Form B (energize to break) configurations are available.

The range features an internal mu-metal screen to eliminate problems that would otherwise be experienced due to magnetic interaction when they are closely stacked.

Four types of dry switches are available, capable of standing-off 1, 1.5, 3 or 4kV d.c. The 3kV version has an increased clearance between the switch and coil pins to accommodate the higher voltage. The 4kV’s higher standoff can improve performance or allow increase in the equipment specification.

Mercury wetted devices are also available for applications where bounce free switching is required. These are rated at 1500 volts d.c. minimum stand-off, 500 volts d.c. switching at up to 50 watts.
