The applied voltage determines the operating level within the selected
range.
4 Volts full scale.
± 0·3% ± accuracy of selected range.
Better than –66dB.
The applied signal selects between Level A and Level B settings.
+ 1·5V nominal. A logic high selects Level B.
Terminal block on rear panel.
Apply +3 to +5 V to disable load input.
The unit will trip into the fault state at nominally 92 Amps.
The unit will attempt to limit the power to approx 335 Watts; if this fails
the unit will trip into the fault state at about 360 Watts.
The unit will conduct a current pulse (to absorb inductively generated
spikes) for 1ms at 90V.
The unit will trip into the fault state at nominally 95V.
Surge suppressors will start to conduct above 120V.
The unit will trip into the fault state if the heatsink temperature exceeds
safe levels.
The unit will trip into the fault state if the external voltage sense is more
than 6V below the internal sense.
The unit will trip into the fault state if the mode is changed while the
input is enabled.
