Safety precautions

The following safety precautions should be observed before using this product and any
associated instrumentation. Although some instruments and accessories would normally be
used with nonhazardous voltages, there are situations where hazardous conditions may be
present.

This product is intended for use by personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid possible injury. Read and follow all ins
operation, and maintenance information carefully before using the product. Refer to the user
documentation for complete product specifi cations.

If the product is used in a manner not specifi ed, the protection provided by the product
warranty may be impaired.

The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of

equipment, for ensuring that the equipment is operated within
limits, and for ensuring that operators are adequately trained.

Operators use the product for its intended function. They must be trained in electrical safety
procedures and proper use of the instrument. They must be protected from electric shock and
contact with hazardous live circuits.

Maintenance personnel perform routine procedures on the product to keep it operating
properly, for example, setting the line vol
procedures are described in the user documentation. The procedures explicitly state if the
operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, perform safe installations, and
repair products. Only properly trained service personnel may perform installation and
service procedures.

Unless explicitly allowed in the specifi cations, operating manual, and instrument labels, do
not connect any instrument to mains.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on
cable connector jacks or test fi xtures. The American National Standards Institute (ANSI)
states that a shock hazard exists when voltage levels greater than 30 V RMS, 42.4 V peak,
or 60 VDC are present. A good s

Operators of this product must be protected from electric shock at all times. The responsible
body must ensure that operators are prevented access and/or insulated from every
connection point. In some cases, connections must be exposed to potential human contact.
Product operators in these circumstances must be trained to protect themselves from the risk

Do not connect switching cards directly to unlimited power circuits. They are intended to be
used with impedance-limited sources. NEVER connect switching cards directly to AC mains.
When connecting sources to switching cards, install protective devices to limit fault current and
voltage to the card.

Before operating an instrument, ensure that the line co

cracks, or breaks before each use.

When installing equipment where access to the main power cord is restricted, such as rack
mounting, a separate main input power disconnect device must be provided in close proximity
to the equipment and within easy reach of the operator.

power is applied to the circuit under test. ALWAYS remove power from the entire test system
and discharge any capacitors before: connecting or disconnecting cables or jumpers,
installing or removing switching cards, or making internal changes, such as installing or
removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under
test or power line (earth) ground. Always make measurements with dry hands while standing on
a dry, insulated surface capable of withstanding the voltage being measured.

For safety, instruments and accessories must be used in accordance with the operating
instructions. If the instruments or accessories are used in a manner not specifi ed in the
operating instructions, the protection provided by the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories. Maximum signal
levels are defi ned in the specifi cations and operating information and shown on the instrument
panels, test fi xture panels, and switching cards.

When fuses are used in a product, replace with the same type and rating for continued
protection against fi re hazard.

onnections must only be used as shield connections for measuring circuits, NOT as

protective earth (safety ground) connections.
If you are using a test fi xture, keep the lid closed while power is applied to the device under test.

Safe operation requires the use of a lid interlock.

If a screw is present, connect it to protective earth (safety ground) using the wire
recommended in the user documentation.

The CAUTION heading with the symbol in the user documentation explains hazards that
could result in moderate or minor injury or damage the instrument. Always read the associated
information very carefully before performing the indicated procedure. Damage to the instrument
may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fi re, replacement components in mains circuits

— including the power transformer, test leads, and input jacks — must be purchased from
Keithley. Standard fuses with applicable national safety approvals may be used if the rating and
type are the same. The detachable mains power cord provided with the instrument may only be
replaced wi
be purchased from other suppliers as long as they are equivalent to the original component
(note that selected parts should be purchased only through Keithley to maintain accuracy
and functionality of the product). If you are unsure about the applicability of a replacement
component, call a Keithley offi ce for information.

Unless otherwise noted in product-specifi c literature, Keithley instruments are designed to
operate indoors only, in the following environment: Altitude at or below 2,000 m (6,562 ft);
temperature 0 °C to 50 °C (32 °F to 122 °F); and pollution degree 1 or 2.

To clean an instrument, use a cloth dampened with deionized wat
cleaner. Clean the exterior of the instrument only. Do not apply cleaner directly to the instrument
or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with
no case or chassis (e.g., a data acquisition board for installation into a computer) should never
require cleaning if handled according to instructions. If the board becomes contaminated and
operation is aff ected, the board should be returned to the factory for proper cleaning/servicing.

Carefully consider and congure the appropriate output‑o󰀨
state, source levels, and compliance levels before
connecting the instrument to a device that can deliver
energy. Failure to consider the output‑o󰀨 state, source

instrument or to the device under test.

Introduction

The Keithley Models 2380-500-30 and 2380J-500-30
programmable high-precision DC electronic load instruments
support constant current (CC), constant voltage (CV), constant
resistance (CR), constant power (CP), and transient operating
modes. Its working power is 750 W. The measurement resolution
of instrument voltage and current are 1 mV and 0.1 mA. The
instruments have adjustable current rise and fall times that range
from 0.0001 A/µs to 1 A/µs. The load current switching speed
reaches up to 50 kHz. The load can be controlled externally
from 0 V through 10 V using analog interfaces. It is equipped
with built-in RS-232, USB, and GPIB ports. The load provides
a special LED mode to conduct a LED power supply test by
simulating an LED current load. The 2380 load also has a Battery
Test mode to discharge a battery and measure the Amp-Hour
capacity of the battery.

The model numbers are 2380-500-30 and 2380J-500-30,
Programmable DC Electronic Load. 500 V, 15 A (rated for 110 V,
230 V, nominal line power).

Complete documentation for the 2380 loads are available for
