2. SPECIFICATIONS
Table 2 contains specifications and operating limits of individual HSF 1200W/1500W Series mod-
els. Table 3 contains specifications and operating limits common to all HSF 1200W/1500W Series
Models. These specifications are at nominal input voltages at 25°C and apply to all models unless
otherwise specified.
RV 18 Remote Voltage - Used with REF, pin 15, for remotely controlling the output voltage (see PAR. 3.4.2)
–PF 19 –Power Fail of open-collector alarm circuit. Used with +PF, pin 16 (see PAR. 3.8.2).
+RC 20 +Remote On-off used with –RC, pin 21, to allow remote turn-on turn-off of the unit (see PAR. 3.6)

(1) See Figure 2 for power derating vs. temperature and input voltage.
(2) 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 combinations
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 Cur-
rent Limit, output voltage restores automatically. If current continues to increase, Overcurrent is triggered. If Overcurrent is com-
bined 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 more than 30 seconds or by opening and (without waiting) reclosing the RC ter-
minals using either the front panel RESET button or an external remote switch.
(5) When overvoltage is detected, output is shut OFF.
(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 2), and bandwidth
≤100MHz.
