Paralleling Diodes Option
The Paralleling Diodes Option allows multiple voltage converters to be connected in parallel to share in powering a
load. To perform this function, each unit is equipped with special output isolation diodes to prevent current from one
unit back feeding into another. In addition, the units’ peak output current is lowered to the continuous rating for safety
purposes.
Units with the Paralleling Diodes option will have the D-designation following model name, in this case VTC805D, is a
VTC805 voltage converter with the paralleling diodes option.
TO SET UP LOAD SHARING:
1. Connect a 1 foot (0.3m) length of appropriate gauge red wire to the positive terminal of each unit. See Installation for
more information about suitable wire gauge.
2. Join these wires to a distribution bus or join them together to a common point.
3. Connect the common point or distribution bus to the load.
4. Repeat the above steps for the negative terminals using black wire and a different common point/distribution bus.
5. The units should now load share. Use a clamp-on ammeter to measure the current to read the current being drawn
from each unit to conrm this. A slight different in current between units is normal.
WARNING: TO PREVENT THE RISK OF HIGH VOLTAGE ELECTRIC SHOCK, NEVER CONNECT OR DISCONNECT
ANYTHING TO THE INPUT OR OUTPUT WHILE POWER SWITCH IS ON.
