General Description

This chapter gives an overview and introduces the features of
the PMC-A Series.
1.1 About This Manual
The PMC-A series come in two types depending on the size of
case. This operation manual describes the following models.
■ Type I
PMC18-1A, PMC18-2A, PMC18-3A, PMC35-0.5A,
PMC35-1A, PMC35-2A
■ Type II
PMC18-5A, PMC35-3A, PMC70-1A, PMC110-0.6A,
PMC160-0.4A, PMC250-0.25A, PMC350-0.2A,
PMC500-0.1A
1.2 Product Overview
The PMC-A Series are compact, high-performance, constant
voltage, constant current Series regulated DC power supplies.
The adoption of Series regulated design realizes a highly stable
output with a low level of output noise. In addition, with an
optional power supply controller, it allows to operate via GPIB
systems which offers wide application in the field of R&D,
Manufacturing, Testing, etc.
PMC-A 17
1.3 Features
● Digital display on both voltage and current at the same
time.
The PMC-A series power supply has two bright LED meters
that display the output voltage, output current, and their set
tings.
● High-resolution setting for output voltage and current.
The variable resistors for the output voltage and current set-
tings are 10-turn wire wound type, allowing high-resolution
settings.
● Output ON/OFF by external contact
The output ON/OFF switch is an electronic switch that emits
no chattering or noise. The switch can also be controlled
remotely.
● External Remote Control
The output voltage and current can be controlled remotely
using an external analog signal (voltage or resistance). By
connecting a power supply controller such as KIKUSUI's
PIA3200 or PIA4810 via the GPIB interface, the PMC-A
series power supply can be integrated into a system such as
an automated test system.
-
● External monitor function
The monitor output enables to monitor the status output, out-
put voltage, and output current from outside of the PMC-A.
● Remote sensing function
The remote sensing function stabilizes the output voltage
across the load. (equipped with 18 V, 35 V models)
● Equipped with overvoltage protection (OVP) function
as standard.
• To control the PMC-A series power supply using
KIKUSUI's PIA3200 (via the GPIB interface), the ROM
version of the PIA3200 must be 1.03 or later. If not, the
18 PMC-A
ROM needs to be upgraded. To have the ROM upgraded,
contact your Kikusui agent or distributor.
• On Type II models, the internal loss is decreased by
changing the input voltage of the series regulator. The
input voltage is changed by switching secondary taps of
the internal transformer using relays. The relay has three
switch points and changes depending on the input volt
age. If the input voltage fluctuates when the output volt-
age of power supply is used near a relay switch point, you
may hear the sound of the relay switching. This is not a
malfunction. When the relay is switched, a spike volt
age at the output voltage may be generated.
1.4 Options
The following options are available for the PMC-A series.
For details, contact your Kikusui agent or distributor.
■ Guard cap (GP01-PMC)
-
-
Exchanged with the knob to prevent inadvertent
operation of voltage or current setting.

General Description
■ Output terminal cover (OTC01-PMC)
Covers the output terminal to prevent unex-
pected accidents. Applies to models with a
rated output of 70 V or greater.
It is recommended that you use the output ter-
minal cover for your safety.
PMC-A 19
■ Handle (CH01-PMC)
A convenient handle for carrying the
power supply.
Applies to all type II models.
■ Rack mount options
The following options are available for rack mount system.
