Atec Kikusui-PCR500 - Manual (Page 3)

Compact design
The PCR-M series is characterized by much
smaller size and lighter weight in comparison with
the ac power supply based on the linear amplifi er.
For example, the very compact PCR-M series is
reduced by a factor of 5 in terms of the volume
and by a factor of about 4 in terms of the weight
(in comparison with our past product). You can
readily handle this product on your desk and
easily carry it.
Output characteristics: AC mode
The output voltage varies from 1 V to 135 V or 2 V
to 270 V (two ranges). You can switch ranges
manually or automatically. The peak current can
triple the maximum rated current for the rectifi er
load of the capacitor input type. The frequency
varies from 40 Hz to 500 Hz, which is why the
PCR500M is suitable as a power supply for
aircrafts and ships that require 400 Hz and for
driving actuators that require 250 Hz.
Output characteristics: DC mode
*1
The output voltage varies from ±1.4 V to 190 V or
±2.8 V to 380 V (two ranges). You can switch
ranges manually or automatically. The maximum
instantaneous current is up to three times higher
t h a n t h e m a x i mu m ra t e d c u r r e n t . W h e n a n
optional interface board is installed, the direct
current can be superposed on the alternating
current (AD + DC mode)
Input characteristics
The input voltage is from 100 V AC to 120 V AC or
200 V AC to 240 V AC at 50 Hz/60 Hz (single
phase). The voltage is automatically determined
when the power supply is turned on. The active
filter enables the power factor to be 0.9 (TYP
va l u e ) t o r e d u c e t h e i n p u t c u r r e n t a n d t h e
harmonic current.
Measurement functions *3
The PCR-M series can measure the voltage,
current, and power of AC and DC output. The
device can display the true RMS and the average
(DC) values for the output voltage, and the true
RMS, peak and the average (DC) values for the
output current. When a communication interface is
used, the PCR-M series can measure the apparent
power (VA), the reactive power (VAR), the power
factor (PF), the crest factor (CF), and the peak
hold current.
Protection
The following protection features are available:
• Protection against non-rated input voltage
• Protection against overheat (OHP)
• Protection against overload:
Current limit (OCP)/monitoring for exceeded
power (OPP)/monitoring for exceeded peak
current
• Detection of voltage abnormalities:
Increased voltage (OVP)/decreased voltage
(LVP)
COMPACT AC POWER SUPPLY
Performance and Features
High-quality output waveform (distortion rate of
output waveform is 0.5% or less)
Output on phase angle
The output on phase angle can be set at AC
mode. The output off phase angle is turned off at
a zero cross phase.
Memory function
*2
The PCR-M series can store three sets of setting
value for output voltage and frequency, and limit
value. By manually changing the preset memory
during output, the test for sudden changes of
voltage and frequency is also possible. When an
optional interface board (IB21, US21 or EX04-
PCR-M) is installed, the memory can store up to
10 settings.
Analog interface
By using an optional analog interface board
(EX04-PCR-M), you can control the output by
external analog signals.
EXT-AC mode
The voltage of the output alternating current can
be changed based on the level input DC signal.
EXT-DC mode
The input waveform is directly amplified and
output.

Control using a PC
You can control the PCR-M series through the
standard RS-232C interface, the optional GPIB
interface, or the optional USB interface.
* By using
the control software (Easy Controller for PCR-M
series) which comes with the PCR-M series, you
can easily set the parameters of the PCR-M
series and log the output measured values.
