2. SPECIFICATIONS
Table 2 contains specifications and operating limits of individual HSF 300W Series models. Table
3 contains specifications and operating limits common to all HSF 300W Series Models. These
specifications are at nominal input voltages at 25°C unless otherwise specified.
+PF 16 +Power Fail of open-collector alarm circuit. Used with –PF, pin 19 (see PAR. 3.7.2.2).
CSB 17 Current Share Bus - Used whenever several power supplies are connected in parallel (see PAR. 5.).
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. 3.7.2.2).
+RC 20 +Remote On-off used with –RC, pin 21, to allow remote turn-on turn-off of the unit (see PAR. 3.5)
–RC 21 –Remote On-off used with +RC, pin 20, to allow remote turn-on turn-off of the unit (see PAR. 3.5)
GND 22 AC input ground
N 23 AC Input neutral
L 24 AC input line

(1) 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 and visual LED indicator.
(2) Using trimpot to attain voltages outside the specified adjustment range may trigger undervoltage (PAR 3.6.4) or 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) Square type. Output voltage returns automatically only if cause is removed within 30 seconds (see PAR. 3.6.2).
(5) 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).
(6) 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.
