General
Guidelines

CAUTION

 Do not place any heavy object on the device.
 Avoid severe impacts or rough handling that

leads to damaging the device.

 Do not discharge static electricity to the device.
 Do not block or obstruct the cooling fan vent

opening.

 Do not perform measurement at circuits directly

connected to Mains (see note below).

 Do not disassemble the device unless you are

qualified as service personnel.

Power Supply

WARNING

 AC Input voltage:

100V/120V/220V/230VAC ±1 0%, 50/60Hz

 Connect the protective grounding conductor of

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

Fuse

WARNING

 Fuse type:

100V/120V: T12A/250V
220V/230V: T6.3A/250V

 Make sure the correct type of fuse is installed

before power up.

SAFETY INSTRUCTIONS

Operation
Environment

 Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (note below)

 Relative Humidity: < 80%
 Altitude: < 2000m
 Temperature: 0°C to 40°C

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The GPE series 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.

Storage

 Relative Humidity: < 70%
 Temperature: −10°C to 70°C

Disposal

Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection

GPE-3060/GPE-6030 User Manual

Overview

The GPE series regulated DC power supply series
are adjustable, multifunctional work stations. It
has three independent outputs: two with
adjustable voltage/current levels and one with
fixed level 5V. The series can be used for logic
circuits where various output voltage or current
are needed, and for tracking mode definition
systems where plus and minus voltages with
insignificant error are required.

Independent /
Series Tracking /
Parallel Tracking

The three output modes, independent, series
tracking and parallel tracking can be selected
through pressing the TRACKING key on the front
panel. In the independent mode, the output
voltage and current of each channel are controlled
separately. In the tracking modes, both the CH1
and CH2 outputs are automatically connected in
series or parallel. CH1 is master and CH2 is slave;
no need to connect output leads. In the series
mode, the output voltage is doubled; in the
parallel mode, the output current is doubled. The
isolation degree, from output terminal to chassis or
from output terminal to output terminal, is 500V.

OVERVIEW

This chapter describes the GPE series in a nutshell,
including its main features and front/rear panel
introduction. After going through the overview,
follow the Setup chapter (page 19) to properly
power up and set operation environment.

Introduction

OVERVIEW

Constant Voltage/
Constant Current

Each output channel works in constant voltage
(CV) or constant current (CC) mode. Even at the
maximum output current, a fully rated,
continuously adjustable output voltage is
provided. For a big load, the power supply can be
used as a CV source; while for a small load, a CC
source. When in the CV mode (independent or
tracking mode), output current (overload or short
circuit) can be controlled via the front panel. When
in the CC mode (independent mode only), the
maximum (ceiling) output voltage can be
controlled via the front panel. The power supply
will automatically cross over from CV to CC
operation when the output current reaches the
target value. The power supply will automatically
cross over from CC to CV when the output voltage
reaches the target value. For more details about
CV/CC mode operation, see page 18.

Automatic
tracking mode

The front panel display (CH1, CH2) shows the
output voltage or current. When operating in the
tracking mode, the power supply will
automatically connect to the auto- tracking mode.
For more details about CH1/CH2 Series Tracking
Mode, see page 30.

Background

According to load condition, The GPE can
automatically switch between constant voltage mode
(CV) and constant current mode (CC).

CV mode

When the current level is smaller than the output
setting, the GPE series operates in Constant Voltage
mode. The indicator for the corresponding
channel appears on the LCD. The Voltage level is kept
at the setting and the Current level fluctuates
according to the load condition until it reaches the
output current setting.

CC mode

When the current level reaches the output setting, the
GPE series starts operating in Constant Current mode.
The indicator for the corresponding channel
appears on the LCD. The Current level is kept at the
setting but the Voltage level becomes lower than the
setting, in order to suppress the output power level
from overload. When the current level becomes lower
than the setting, the GPE series goes back to the
Constant Voltage mode.

FAQ

GPE-3060/GPE-6030 User Manual

Q1. I pressed the panel lock key but the output still turns on/off.

A1. For safety reasons the output key is not affected by the panel key
lock feature.

Q2. The CH3 overload indicator turned on – is this an error?

A2. No, it simply means that the CH3 output current reached the
maximum 5.2A and the operation mode turned from CV (constant
voltage) to CC (constant current). You can continue using the power
supply, although reducing the output load is recommended.

Q3. The specifications do not match the real accuracies.

A3. Make sure that the power supply is powered on for at least 30
minutes, within +20°C ~ +30°C.
