Item Signal Description
Sense LO Voltage remote sense input terminals. Used to compensate for I*R voltage drops in cable leads, connectors, and switches.
Output LO LO force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.
Output HI HI force terminal connected to channel power stage (generates and/or dissipates power). Positive polarity is defined as voltage measured on HI > LO.
Sense HI Voltage remote sense input terminals. Used to compensate for I*R voltage drops in cable leads, connectors, and switches.
Chassis ground Tied to chassis ground through module front panel. Use for connections to cable shields or grounding the LO force terminal.
Note Front panel connectors can accept wire gauges from 12 AWG to 24 AWG.
