SERIES/PARALLEL

62000H Series DC Power Supplies with Solar Array Simulation are able to operate in series
or parallel when in the common CV/CC MODE. The voltage is up to 1200V if connecting in
series and the current is up to 250A if connecting in parallel. When the IV curve function is
enabled that is in TABLE Mode, SAS Mode and IV PROGRAM Mode, only parallel
connection is supported with no series connection.

Series/Parallel cannot be mixed in use. A620028 and A620027
models support parallel connection only.
The maximum output voltage or current is 1200V or 250A when
operating the 62000H Series with Solar Array Simulation in series or
parallel. Table 3-1 lists the example of 62150H-600S.

Different model is unable to be operated in parallel or serial.
Be sure the breaker capacity is enough and the earth wire is
grounded to earth ground when series/parallel is in use.
When the devices to be paralleled are over 5 sets (>5), please
contact the Service Center or agent of CHROMA.
Please configure the DC Power Supplies up and down stack for
parallel connection. The standard CURRENT SHARING cable is
unable to use if placing the devices lateral for parallel configuration.
It is necessary to purchase another optional CURRENT SHARING
(100CM) cable for use. Please contact CHROMA Service Center or
local agent for further information. Also, be noted that the paralleled
devices cannot exceed 2 units when placing lateral.
Firmware version 2.00 or above is not backward compatible. Be
sure to upgrade the device with firmware 1.XX to 2.00 when
connecting to a device with firmware 2.00 for series or parallel
operation. Please contact the service unit for firmware upgrade.
