General Guideline

CAUTION

• 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 categories and their requirements as follows. PSH falls under category II. Measurement category IV is for measurement performed

• Input voltage: 90 ~ 250 V AC, 50/60 Hz

• The power supply voltage should not fluctuate

more than 10%.

• Connect the protective grounding conductor of

the power cord to earth ground, to avoid electrical shock.

• Make sure the correct type of fuse is installed

before powering up.

• Replace the fuse with the specified type and

rating only, for continued fire protection.

• Disconnect the power cord before fuse

replacement.

• Make sure the cause of the fuse blowout is

fixed before fuse replacement.

• Disconnect the power cord before cleaning.

Operation Environment

WARNING

Storage Environment

xylene, and acetone.

Location: Indoor, no direct sunlight, dust free, almost non-conductive pollution (Note below)

Relative Humidity: < 85%

Altitude: < 2000m

Temperature: 0°C to 40°C

Input Breaker Capacity: Over 20A (PSH-10100A, 2050A, 3630A, 6018A)

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.

Remote Sensing and Local Sensing

Remote sensing compensates the cable loss between PSH and load, up to 0.5V. Use remote sensing whenever the load voltage has to be accurate.
