Cynergy3's D200 series combines high-power 200 W switching capacity with 7 kV isolation across the contacts. The switching performance is achieved through the use of high-vacuum reed switches and tungsten contacts. These normally-open (NO) relays are capable of switching voltages up to 2.5 kV. They can also carry currents up to 5 amps. Models are available with 5 V, 12 V, and 24 V coil operation.
