1 Outline
Outline of Product
The high power factor PWM converter with power
regenerative function, the RHC-D series is used in
combination with a Fuji inverter to return the
regenerative energy generated on the load side to the
power source, improving the regenerating performance
and saving energy.
The converter shapes an input current waveform into a
sinusoidal waveform to enable driving at a power factor
of 1 so that it is possible to reduce the capacity of the
power supply equipment.
As well, the converter is useful for the replacement of
conventional applications using braking resistors, such
as cranes and vertical transfer machines and it is
compliant with the "Guideline for Suppressing
Harmonics by Customers Receiving High Voltage or
Special High Voltage" (conversion coefficient Ki = 0).
With simplified operation, it is possible to monitor the
input power supply, current, power, and load factor,
configure function codes, and check alarm history.
Various communications options provided allow you to
monitor data from a remote site easily or to integrate
the converter in the customer's system without
difficulty.
The converter also applies to large capacity,
low-voltage inverters by controlling sharing of load to
the inverter uniformly with the parallel connection
option and input transformer.
Guideline for Suppressing Harmonics
The PWM control regulates the power supply current
into a sinusoidal wave to contribute to substantial
reduction of harmonic currents.
Accordingly, the combination with an inverter can
handle the conversion coefficient Ki (specified in the
"Guideline for Suppressing Harmonics by Customers
Receiving High Voltage or Special High Voltage" issued
by the Ministry of Economy, Trade and Industry) as "0"
(that is, no generation of harmonics).
Possible to Reduce the Capacity of Power
Supply
By controlling the power factor, the converter supplies
the in-phase current relative to the power phase voltage,
enabling running at a power factor of 1. This makes it
possible to reduce the capacity of the power transformer
or the size of the devices to less than those of the
standard inverters.
Substantial Increase of Braking
Performance
The regenerative energy obtained in frequent
acceleration/deceleration operation or elevator returns
to the power supply side, promoting energy savings.
Since the waveform of the regenerative current is
sinusoidal wave, too, there is no need to be anxious
about trouble in the power supply system.

3.2 Installation and Layout
• Prevent lint, paper fibers, sawdust, dust, metallic
chips, or other foreign materials from getting into
the converter and filter stack or from accumulating
on the heat sink.
Otherwise, a fire could occur.
• Do not install or run a damaged converter or filter
stack. There should be no parts missing.
Injury may result.
• Install the converter in a panel or at places where
people can not touch it easily.
Electric shock or injury may result.
1) Install the converter and filter stack vertically to a
robust structure with specified bolts so that the
"PWM CONVERTER" and "FILTER STACK"
characters are visible correctly in front, respectively.
Do not install them upside down, horizontally, or at
an angle.
2) Do not place devices or components in front of the
converter. The converter has the display and
operating unit on the front and wiring or
maintenance/inspection requires removing the front
cover.
3) Ensure that the minimum clearances and air channels
shown in Figure 3.2-1 are maintained al all time for
ventilation since the converter and filter stack
generate heat during operation.
The generated heat goes up, so do not route cables or
wiring in the space above the converter and filter
stack.
• Do not place flammable objects near the converter
or filter stack.
Fire may result.

Clearances
4) Follow Fig. 3.2-2 about clearances of between stacks
of Phase-specific
5) The converter generates heat in running. When
mounting the converter in a control panel, therefore,
take extra care with ventilation inside the panel to
prevent the ambient temperature from exceeding the
specified limit. Do not install the converter in a small
airtight box with poor ventilation.
6) The generated heat is radiated upwards by fans inside
the converter and filter stack. Do not install the
converter or filter stack beneath devices sensitive to
heat.
• Install the converter and filter stack on a base made
of metal or other non-flammable material.
Fire may result.
7) When the converter is running, the temperature of
the heat sink rises to in the vicinity of 90qC. The
mounting surface of the heat sink on the back side of
the converter and filter stack should be made of
material being proof enough against the temperature
rise.
• Prevent lint, paper fibers, sawdust, dust, metallic
chips, or other foreign materials from getting into
the converter or from accumulating on the heat
sink.
Otherwise, a fire could occur.
• Keep away from the heat sink, filtering resistor,
filtering reactor and boosting reactor because they
become very hot.
Burns may result.

1) Do not install stacks one above the other.
2) In space "C" (above the stack's outlet fans),
only a fuse (authorized by Fuji Electric) can
be mounted.
To mount general devices in the space,
select devices whose maximum operating
temperature is 70qC and mount them so that
they do not interfere with the outlet fans.
3) In space "D" (beneath the stack's inlet), do
not block approximately 60% of the area in
350 mm clearance. To install devices in
space "D," ensure 100 mm clearance.
