Cleaning
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 0°C to 40°C
Humidity: 0 to 85% RH
Altitude: <2000m
Overvoltage category II
(Pollution Degree) EN 61010-1specifies the pollution degrees and
their requirements as follow. The instrument 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
Temperature: -20°C to 70°C
Humidity: <90% RH
Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to

PEL-3000A/AH Series Introduction
The PEL-3000A/AH Series is a family of high performance DC
electronic loads positioned to test a wide range of different power
sources. The DC electronic loads are fully programmable to
simulate anything from basic static loads to complex dynamic loads.
With the ability to operate independently or in parallel, the PEL-
3000A/AH Series is extremely robust and capable of molding to
any test environment.
Please note that throughout this manual the term “PEL-
3000A/AH” refers to any one of the models in the series lineup,
unless specifically stated otherwise.
