Unless otherwise noted, specifications apply to both M and MZ models.
(1)
M Models only
: To adjust output voltage down to approximately 0V use external voltage source or resistance (see PAR.
3.4.2). Refer to Table 4 for minimum conditions required to maintain proper operation of alarm relay, meter and visual LED
indicator.
(2)
If the visual LED indicator is powered from the HSF output (see PAR 3.4.3), refer to Table 5 for minimum conditions required
to maintain functionality of the indicator.
(3)
Using trimpot to attain voltages outside the specified adjustment range may trigger undervoltage (PAR 3.7.4) or overvoltage
(PAR 3.7.1) 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).
(4)
See Figure 2 for power derating.
(5)
Square type. Output voltage returns automatically only if cause is removed within 30 seconds (see PAR. 3.7.2).
(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)
Ripple and noise levels above are satisfied when conditions are 0 to 100% load, 0 to 40°C (load is derated from 40 to 55°C,
see Figure 2), and bandwidth
100MHz.
(8)
Range shown is operating range; minimum range upon startup is 0.5V higher than minimum operating range shown.
