Parallel Operation
DC modules capable of parallel operation are available as the
C130X24 C130X36 model. Be sure to pay attention to
following notes when operating in parallel using the DC
modules.
1. When using the DC modules with adjusted output voltage, all
DC modules to be connected in parallel must be adjusted inde-
pendently. When adjusting using the output adjuster, ensure there
are no bus bars bridging between different DC modules before
rotating the output adjuster. Upon completion of adjustment of
the output voltage, then please install the bus bars.
2. When connecting the output terminals, be sure to connect only
terminals with the same electrical polarity characteristics to the
same bus bar.
3. When installing DC modules in parallel operation configu-
ration in a base power unit, be sure to use only slots that are
designed for parallel operation in the base power unit, as per the
following table:
Slots corresponding to parallel operation
C300 C450 C650
Slot 1 ○○○
Slot 2 ○○○
Slot 3 ○○○
Slot 4 ○○○
Slot 5 ○×
○: Compatible with parallel operation
×: Not compatible with parallel operation
4. When using the products with a dynamic load, be sure to apply
full evaluation and testing in the application before using.
CAUTION: The products are not compatible
with series operation. Be sure not to use the
products in a series configuration.

SANKEN ELECTRIC CO., LTD. December 2016PAN40004-001E-02
Input Voltage Range, Harmonic Current, and
Inrush Current
Input voltage range
The input voltage range of a base power unit is 85 to 264 VAC.
If other than specified input voltages are applied, it could cause
the products to fail to operate within the specifications and/or
cause permanent failure of the products.
Harmonic current
A harmonic current suppression circuit (active filter) is incorpo-
rated into each base power unit, and harmonic current is sup-
pressed in all load conditions from no load to full load. The input
voltage range at which the harmonic current suppression circuit
activates is between 85 and 264 VAC.
Inrush current
If a switch is used for controlling input, be sure to select a switch
that can withstand the expected inrush current. If the AC sup-
ply is being switched off and on again, before reapplying power
wait until the internal cooling fan has stopped moving, otherwise
a large current could flow after release of the inrush preventive
circuit.
Protection Functions
Overcurrent protection (OCP)
Each DC module has an isolated overcurrent protection circuit
incorporated into it. When OCP is activated, it shuts down the
respective DC module. If output is stopped due to an overcurrent
condition, be sure to evaluate the load condition and remove the
causes of overcurrent before reapply AC either by remote on/off
or by input of the base power unit.
!
CAUTION: OCP does not necessarily
guarantee complete protection against any
short in the output circuit. Be sure not to short
the output when using the products.
!CAUTION: Regardless of the OCP range, be
sure not to exceed total rated output current
range or rated output power of the products.
Overvoltage protection (OVP)
Each DC module has an isolated overvoltage protection circuit
incorporated into it. When OVP is activated, it shuts down all
output. If output is stopped due to an overvoltage condition, be
sure to shut off the input and delay reapplying the AC supply
until more than 30 seconds after removal of the causes of the
overvoltage condition.
Thermal shutdown protection
Each base power unit has a thermal shutdown protection circuit
incorporated. The circuit is activated when the following abnor-
malities occur:
• When the airflow volume of the internal fan is lowered and/or
stopped, the internal temperature rises.
• When the base poser unit is used for a long time in conditions
exceeding the total rated power.
• When the base power unit is used in an ambient temperature
exceeding specified temperature in the specifications.
When thermal shutdown is activated, it shuts down all output.
Be sure to shut off the AC supply and remove the causes of the
overheating, as well as delay long enough for the products to cool
to normal temperatures, before reapplying the AC supply. If the
application requires that the product be used continuously, be
sure to apply thorough investigation of the causes and counter-
measures for overheating before using the product.

Output voltage adjustable range and remote
sensing
Output voltage adjustable range
Each DC module has either one or two output voltage adjusters.
Rotate the adjuster clockwise to increase the output voltage and
counterclockwise to decrease the output voltage. When adjusting
the output voltage, be sure not to exceed either the rated output
power of the system, or the rated output current of the module.
The output voltage adjustable range varies for each DC module.
Please ascertain the specification of each DC module before
using.
Remote sensing
Some DC modules incorporate remote sensing function. Remote
sensing functions allow the system to compensate for voltage
reduction due to output wiring. The range of voltage compensa-
tion available varies according to DC module, as shown in the
table at right.
When using remote sensing, be sure to conduct a thorough evalu-
ation and adjustment of the application system, based on the
remote sensing connection example shown.
Be sure to pay attention to following notes when using the remote
sensing function:
• Be sure to use thick wire, with a sufficient current capacity
margin above the maximum output current for wiring from power
supply to the load. Set the line drop to the compensated voltage or
below.
• Oscillating waveforms and/or fluctuations of output voltage
could arise due to wiring and load impedance. Be sure to apply a
thorough evaluation before using the products.
!
CAUTION: When a bad connection (for
example, caused by a loose screw) of a
load wire arises, the load current flows
into the remote sensing wire and it could
cause damage to the power supply due to
overheating. Be sure to pay attention when
connecting wires.
