Output Terminals
Mate with round or Y terminals with max OD of 6.75 mm and max ID of 3.9 mm
Terminal Size: (2) M3
Torque: 3 kgf-cm
Mounting Clearance
Allow at least 4 mm side clearance and 5 mm height clearance. If clearances aren’t met, the isolation and withstand
specifications may not be met.
Field Ground
Should be connected to the earth (ground) terminal of the apparatus otherwise conducted noise and output noise will
increase.

APPLICATION NOTES
On/off Remote Control
A PS On/Off remote control is provided in CN4. See Figure 1 for the PS-ON diagram and control function.
Figure 1
VMS-300A
Note: Power on: VPS-ON ≤ 2V, IPS-ON ≥ 2 mA
(PS-ON and GND short, IPS-ON = 4.5 mA typical)
Power off: Open circuit, VPS-ON = 11~16 V
When the PS On/off remote control function is not
used, connect a short circuit between the PS-ON
control & the signal GND.
Output Remote Sensing
The VMS-300A series can remotely sense both lines of the output. The feature moves the effective voltage regulation point
from the output of the unit to the point of connection of the remote sense pins. This feature automatically adjusts the real
output in order to compensate for voltage drops in distribution and maintain a regulated voltage at the point of load. The
remote sense voltage range is as follows:
[(+Vout) – (-Vout)] – [(+Sense) – (-Sense)] ≤ 10% Vo_nominal
If the remote sense is not used, the sense pins should be connected locally to the respective Vout pins. The remote sense pins are located
on CN4.
