Current limit value determined by the combination of input voltage and output voltage setting. For example, if RKE 48-23K is
operated at 120V a-c and output voltage is set at the minimum of output range (33.6V), current limit is closer to the maximum
specified value of 36.8A. For the same input voltage (120Vac) if output voltage is set at maximum (55.0V), then the current
limit value is closer to 20A (the minimum current limit value specified for input voltage range 90-170V a-c).
(3)
Winker (intermittent) Operation; after cause is removed, output voltage restored automatically, however for some combina-
tions of input voltage and output voltage and current limit characteristics may be square type: see note (4) below.
(4)
Square type. Unit first enters Current Limit; output voltage starts to drop (nearly square curve). If cause is removed while in
Current Limit, output voltage restores automatically. If current continues to increase, Overcurrent is triggered. If Overcurrent
is combined with an output voltage drop below 60% of rated output voltage (below 5V for 36V model), the unit shuts OFF;
recovery is by removing, then reapplying input power after approximately 30 seconds or by opening and (without waiting)
reclosing the RC terminals.
(5)
When overvoltage is detected, output is shut OFF. Recovery is by removing, then reapplying input power after approximately
30 seconds or by opening and (without waiting) reclosing the RC terminals.
(6)
Ripple and noise levels above are satisfied when conditions are 0 to 100% load, 0 to 65°C (load is derated from 50 to 65°C,
see Figure 3), and bandwidth
≤100MHz.
