(1)
To adjust output voltage down to approximately 0V requires that DIP SW1, position 7 be set to ON. Refer to Table 5 for mini-
mum conditions required to maintain proper operation of alarm relay, meter (AM Models only) and VDC ON/ALARM indicator.
(2)
Using trimpot to attain voltages outside the specified adjustment range may trigger overvoltage (PAR 3.6.1) faults. Recovery
is by removing, and after approximately 40 seconds, reapplying AC input power or by reset (open and close) at ±RC terminals
(no delay).
(3)
See Figure 2 for power derating.
(4)
CAUTION: The unit may be damaged if operated under overcurrent or shorted conditions for more than 30 seconds. If current
exceeds limit (5% of nominal), output voltage starts to drop. If overload condition continues, current up to 130% of nominal
may be experienced.
(5)
Constant current limit with automatic recovery (see PAR. 3.6.2).
(6)
When overvoltage is detected, output is shut OFF. Recovery is by removing, and after approximately 40 seconds, reapplying
AC input power or by reset (open and close) at ±RC terminals (no delay).
(7)
Measure with JEITA RC-9131A probe, bandwidth of scope: 100MHz.
