Using in Series/Parallel Operation
Parallel Operation
A maximum total of 10 power supply outputs can be connected parallel to increase the output current.
Further, Master-Slave Parallel Operation, the controlling of the overall output voltage and current with a single
Master, is available.
Simply connect using a parallel control cable to enable automatic detection of the number of parallel devices.
The measurement value, the total sum of the output current and output power, is displayed on the Master unit.
Connection
Connect as shown in the below diagram.
Connect from the first unit’s (Master) M/B CONTROL Connector OUT to the second unit’s (Slave) M/B CONTROL
Connector IN. Connect from the second unit’s M/B CONTROL Connector OUT to the third unit (Slave).


Parallel operation is only possible with the same-voltage HX-S-G2 series models.
(Ex: Parallel operation of HX-S-030-200G2 and HX-S-030-400G2 is possible.)

FUNCTION items for when operating in Slave cannot be set by only references.

When operating in Slave, the only valid keys during an alarm reset are the "RESET", "FUNC", and "LOCAL" keys.

Do not set to OPEN when wiring connections between power supplies with minus output terminals.

Turn all parallel connected HX-S-G2 Series’ input power (POWER switch) ON.

When using, attach the earth wire of parallel connection cable to the M/B FG terminal.

CAUTION
● Parallel control cable (HXP-***M) Please connect so that it does not block the rear air discharge port.
●
In the figure, chronicle is done to make it easier to understand the connection.
●When wiring from each HX-S-G2 power supply to the load,use wires equal in length
and cross-section area. Also , wire as short as possible. If the distance to load is
approximately 10m or more, parallel connect to a relay terminal block etc. before
connecting to load
