Channel to Channel Isolation
Voltage
Any output can be floated up to 240 V (DC + peak AC with AC limited to a
maximum 3 Vpk-pk and a maximum of 60 Hz) relative to any other channel
terminal. Remote sense terminals should remain within 1 V of their respective
outputs to avoid possible damage.
Channel to Ground Isolation
Voltage
Any output can be floated up to 240 V (DC + peak AC with AC limited to a
maximum 3 Vpk-pk and a maximum of 60 Hz) relative to the earth ground
terminal. Remote sense terminals should remain within 1 V of their respective
outputs to avoid possible damage.
