(1) Using trimpot to attain voltages outside the specified adjustment range may trigger undervoltage or overvoltage faults.
(2) 0V is approximate (logic 0: 0.0 - 0.4V d-c).
(3) Observe minimum for proper functioning of alarm relay, optional meter and LED.
(4) When undervoltage or overvoltage is detected, output is shut OFF. Recovery is either by opening, then reconnecting, short across RC terminals (no delay), or by removing, and after approximately 40 seconds, reapplying a-c input power.
(5) See Power vs. Temperature for power derating.
(6) Constant current limit with automatic recovery, except 5V model: constant current limit with hiccup and automatic recovery.
(7) Measure with JEITA RC-9131A probe, bandwidth of scope: 100MHz.
(8) Internal DIP SW 1, position 7, controls front panel adjustment range: ON allows adjustment down to zero, OFF allows adjustment down to approximate Minimum Adjustment value.
(9) For model HSF 5-60AM, 3V d-c minimum output is required for VDC ON/ALARM indicator to function, no minimum required for alarm relay and meter to function. VDC ON/ALARM indicator brightness is dimmer than other models (this is normal).
(10) Current Limit setting.
(11) 0C ≤ 70C/-10C ≤ 0C
