PROTECTION
Excess Power: The unit will attempt to limit the power to 430 Watts; if this fails the unit
will trip into the fault state at 460 Watts.
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 20 Amps.
The unit is protected by fuses that protect the unit against currents that
exceed 20A. This is primarily as
a protection against high power sources
with a current capability of >20A being connected to the load with
reverse polarity.
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 510V.
The unit will trip into the fault state at nominally 530V. Surge
suppressors will start to conduct at typically 800V ± 20%.
Temperature: The unit will trip into the fault state if the Mosfet temperature exceeds
safe levels.
Reverse Polarity: The unit will trip into the fault state if a reverse current is drawn that
exceeds 200mA. The unit is protected fuses that protect the unit against
currents that exceed 20A.

Specification Notes
(1)
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.
(2)
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 25V and a
minimum current of 200mA. The actual performance attainable with electronically regulated
power supplies depends on the combination of source and load loop bandwidths and
interconnection inductance.
