Remote Disable Input
Connection:
Terminal block on rear panel.
Input to the LED of an opto-isolator through 1k
Ω
resistor.
Threshold:
Apply >+3V to disable the load input. Max. Voltage 12V.
PROTECTION
Excess Power:
The unit will attempt to limit the power to approx 430 Watts; if this fails
the unit will trip into the fault state at about 460 Watts. If intermittent
mode operation is enabled, these levels are 610 W and 630 W.
Protection Current:
The input is disabled if the measured current exceeds a user set limit.
Excess Current:
The unit will trip into the fault state at nominally 92 Amps.
Protection Voltage:
The input is disabled if the measured voltage exceeds a user set limit.
Excess Voltage:
The unit will conduct a current pulse (to absorb inductively generated
spikes) for 1ms at about 90V.
The unit will trip into the fault state at nominally 106V
Surge suppressors will start to conduct above 120V.
Temperature:
The unit will trip into the fault state if the heatsink temperature exceeds
safe levels.
Sense Error:
The unit will trip into the fault state if the external voltage sense is more
than 6V below the internal sense.

Specification Notes
(1)
In 600 Watt short-term operation mode the dynamic response is not specified, and both the
slew rate and the transient oscillator frequency range are restricted. The slew rate limitation
applies also to external voltage control. This mode is primarily intended for limited duration
operation at a fixed level setting.
(2)
Slew Rate Ranges refer to the theoretical slope of the transition between two levels,
regardless of whether that transition can be achieved when taking into account the level
difference, the set transition duration, the minimum transition time, and the characteristics of the
source.
(3)
Minimum Transition Time specification is an indication of the fastest available transition using
a benign source and low inductance connections, with a minimum terminal voltage of 5V and a
minimum current of 1A. The actual performance attainable with electronically regulated power
supplies depends on the combination of source and load loop bandwidths and interconnection
inductance.
(4)
The common mode capability of the current monitor is to provide tolerance of voltage drops in
cables. The monitor negative must be connected at some point to the load negative circuit.
