| (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. Models with Z suffix do not require a minimum adjustment 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).
