The N2267A is designed for highcurrent (up to 8 A continuous), lowresistance switching applications, such as AC/DC power supply testing. It can also be used to switch on/off AC (up to 250 V) or DC (up to 125 V) Bpower supplies and current sources. Each channel can carry 8 A current at the same time.

For thermal protection and reliability, the N2267A has built-in temperature control circuitry that uses sensor ICs and a cooling fan. An over-temperature warning signal is also available to activate an external LED or buzzer.
