Functional Description
Parallel operation
Parallel operation can be performed only with the HWB060S
models. Please contact Sanken if you intend to perform parallel
operation. Sanken provides this function as a special feature.
During parallel operation, each unit must be operated within 90%
of rated current. Connect Schottky barrier diodes to the units as
shown in the diagram to balance the output currents of all units
during parallel operation. Select diodes having withstand voltage
more than the output voltage and having current capacity that is
more than output current (Sanken FMJ-2303, 30V 30A recommended).

Note: When designing the application, be sure to provide for dissipation of the self-generated heat from the diodes.
Adjust and check the output voltage of each power supply to
ensure that the same voltage is reached. Use load wires with
the same thickness and length to balance output power of each
power supply.
Series operation
The HWB series can be connected in series, as shown in the
diagrams. For configurations where diodes are required, select
Schottky barrier diodes which are rated to handle the expected
output current flow when the output voltage rises to the breakdown level. Current should not flow through the diodes during
normal operation at steady state.

Remote On/ Off
Circuit Requirements
HWB (with
remote on/off option)
For remote control of output on/off switching, HWB units with
the R option must be used. An external power supply (5 to 24 V)
also is required. An external switch is used to control the input
from the external power supply. In the example diagrams, use of
an optoisolator and a transistor are shown.
The output is enabled by applying voltage (4.5 to 30 VDC) to the
RC terminal. The range of inflow current from the external power
supply is from 1.5 to 5 mA (typ). The voltage differential between
the RC and –V terminals must be 30 V or less.

• For remote control of an individual HWB single output unit,
connect the RC terminal to the positive terminal of the external
power supply and the –V terminal to the negative terminal of the
external power supply and to the GND terminal of the load.
• For an individual HWB dual output unit, connect the RC terminal to the positive terminal of the external power supply and the
0V terminal to the common of the load.

Installation
Mounting
Adequate free air space is mandatory to allow convective airflow
to cool the unit. If the cooling effect is insufficient, output could
stop.
• Ensure there is free airspace clearance both at the back and
top of the unit. The unit must be mounted vertically to allow for
convection current flow. See illustration below.
• Mounting flanges are provided at the front and rear of the unit.
Insert a screw at the rear of the rack shelf and slide the unit slot
around the screw. Then fasten a screw through the screw hole in
the flange at the front of the unit. Then tighten the rear screw to
the slot.
• If the product is used in a dusty environment, an air filter may
be required and the filter may affect ventilation efficiency. In
such situations, derating could be required. Please consult with
Sanken for the details.

Derating
Derating is applied to each power unit independently. To prevent
the load factor from being truncated due to the derating, make
sure the power unit is used within specification, considering both
derating of total rated power of the unit and adjacent sources of
heat or interference with cooling air flow.
The derating characteristic of the products at various ambient
temperatures is shown in the chart below.
