• Do not place any heavy object on PSH.
• Avoid severe impacts or rough handling that
leads to damaging PSH.
• Do not discharge static electricity to PSH.
• Do not block or obstruct cooling fan vent
opening.
• Do not perform measurements at power source
and building installation site (Note below).
• Do not disassemble PSH unless you are
qualified as service personnel.
(Note) EN 61010-1:2001 specifies the measurement

This is a Class A product which may cause radio
interference in a domestic environment. In such
case, take adequate measures.
(Note) EN 61010-1:2001 specifies the pollution degrees
and their requirements as follows. PSH falls under degree
2.
Pollution refers to “addition of foreign matter, solid,
liquid, or gaseous (ionized gases), that may produce a
reduction of dielectric strength or surface resistivity”.
Pollution degree 1: No pollution or only dry,
non-conductive pollution occurs. The pollution has no
influence.
Pollution degree 2: Normally only non-conductive
pollution occurs. Occasionally, however, a temporary
conductivity caused by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry,
non-conductive pollution occurs which becomes
conductive due to condensation which is expected. In
such conditions, equipment is normally protected against
exposure to direct sunlight, precipitation, and full wind
pressure, but neither temperature nor humidity is
controlled.
Location: Indoor
Relative Humidity: < 70%
Temperature: −10°C to 70°C
• Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into PSH.
• Do not use chemicals or cleaners containing
harsh materials such as benzene, toluene,

Safety Instructions
Power cord for the United Kingdom
When using PSH in the United Kingdom, make sure the power
cord meets the following safety instructions.
NOTE: This lead / appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with the colours
marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with the letter E or by the earth symbol
or Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is
marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked
with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact
the supplier.
This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or user
instructions for details. As a guide, cable of 0.75mm2 should be protected by a
3A or 5A fuse. Larger conductors would normally require 13A types,
depending on the connection method used.
Any moulded mains connector that requires removal /replacement must be
destroyed by removal of any fuse & fuse carrier and disposed of immediately,
as a plug with bared wires is hazardous if a engaged in live socket. Any
re-wiring must be carried out in accordance with the information detailed on
this label.

PSH Overview
PSH Series are modular-type programmable
switching power supplies designed for broad
range of applications. The series consists of 12
models, output ranging from 360W to 1000W.
Switching technology and built-in PFC control
give PSH higher power efficiency, power density,
and power factor compared with other linear
power supplies. Protection mechanisms keep the
output voltage, current, and temperature within
limit. Remote control interface equipped with
SCPI command set and Lab-View Driver
facilitates ATE software development.
This chapter describes PSH series features and
appearances in a nutshell.

To avoid excessive cable loss, shorten the
distance between PSH and load as much as
possible. Remote sensing compensates cable
loss up to 0.5V.
To minimize noise effect and load line
impedance, use shielded pair wiring. Twisted
wires are more effective, especially for remote
sensing.
Load Configuration
Select the appropriate configuration for the target application.

PSH User Manual
Constant Voltage/ Constant Current
Crossover Characteristic
PSH series automatically switch
between constant voltage mode
and constant current mode,
according to the load change.
When the load current is
smaller than the limit (I
SET),
PSH operates in Constant
Voltage mode, changing the
current level according to the
load but keeping the Voltage
level at the limit (V
SET).
When the load current is the
same as the limit (I
SET), PSH
operates in Constant Current
mode, changing the Voltage level
according to the load but
keeping the Current level at the
limit (I
SET).
Let’s take recharging a 12V battery as an example. PSH output
setting is 13.8V, 1A. An empty battery puts a heavy current load
on the power supply. PSH starts running at Constant Current
mode, supplying full 1A current but keeping the voltage lower
than 13.8V. As the battery becomes charged, the load also
becomes smaller. PSH then switches to Constant Voltage mode,
supplying less than 1A current but supplying full 13.8V.

The actual output is lower than the setting.
The cable loss might be causing the load voltage
lower than the setting. Upgrade the output cable
to a better capacity and/or use the remote sense
to compensate for the voltage drop. See page25
(theory) and page25 (cable assembly).
The actual output is much higher than the setting.
The remote sensing (page24) compensates for
the cable loss for up to 0.5V. If the output level
goes much higher, the remote sensing terminal
might be disconnected. Make sure the
connection is secure. See page32 for details.
