PROGRAMMABLE DC electronic load
MODEL 63600 SERIES
Chroma's 63600 series DC electronic loads
are designed for testing multi-output AC/DC
power supplies, DC/DC converters, chargers,
batteries, adapters, and power electronic
components. They are excellent for research,
development, production, and incoming
inspection applications.
instrument allows up to 100 sets of system
operating status which can be stored in the
EEPROM and recalled instantly for automated
testing application.
The 63600's state of the art design uses DSP
technology to simulate non-linear loads using
a unique CZ operation mode allowing realistic
loading behavior.
Real time measurement of voltage and current
are integrated into each 63600 load module
using a 16-bit measurement circuit with three
current ranges. The user can perform online
voltage measurements and adjustments or
simulate short circuit tests using the simple
keypad on the front panel.
The 63600 series can draw its rated current
under very low voltage (0.4V typical). This
unique feature guarantees the best loading
performance for modern Point-of-Load conditions and fuel cells.
With the VFD display and rotary knob,
the 63600 loads offer versatile front panel
operation. Users are able to control the 63600
family remotely via Ethernet, USB, or GPIB
interface.
The 63600 series can simulate a wide range
of dynamic loading applications, with programmable load levels, slew rates, duration, and
conducting voltage. The 63600 also has a
dynamic sweep function to meet the test
requirements of ATX power supplies. The
Also included in the 63600 are self-diagnostic
routines and full protections against OP, OC,
OV, OT and reverse polarity. This ensures the
quality and reliability of the 63600 and provides
protection to units under test.

Versatile System Configuration
Chroma's 63600 Series Programmable Electronic Load integrates micro-processing capability into each load module to optimize the speed and
control among multiple load modules. All load modules are configured to work independently, though testing can be carried out simultaneously
at multiple outputs via remote control to simulate real life application.
Module Load Design
The Chroma 63600 electronic load mainframe accepts the user-installable
63600 series load modules for easy system configuration. The model
63600-5 mainframe holds five 63610 load modules to offer up to 10 100W
load input channels with standard front-panel inputs. The maximum power
for a single mainframe is 2kW when five 63640-80-80 load modules
are paralleled. This is suitable for testing multiple output switch mode
power supplies, and many other types of power products. Using the GO/
NG output port, production snapshots are made available to show the
immediate pass/fail judgment of UUT. All modules on the mainframe share
a common GPIB address to synchronize and speed up the control of the
load modules and read back the operating data.
Application of Specific Load Simulation
The 63600 series load modules operate in constant voltage, current, resistance, power, or impedance to satisfy a wide range of test
requirements. For example, the CV is designed to simulate batteries for charger testing.

Low Voltage Operating Characteristics
Each 63600 load module provides 3 load current range settings with a
minimum full current operating voltage of 0.5V for each range. At the

minimum voltage (0.4V), the 63640-80-80 series load can draw maximum
current defined by the current range. Based on this design, this load is well
suited for testing DC/DC converters, fuel cells, and other low voltage - high
current devices. Low voltage operation is possible towards zero volts with
corresponding reduced current levels (see de-rating curves).

The dynamic mode provides a unique simulation capability, which allows users to set the number of repeat times, and setting range is
1 – 65535, it is idea to test the Peak Current sustained of D2D converter.
The 63600 also offers a unique dynamic frequency sweep with variable frequencies up to 50kHz ideal for use in finding the worst case of UUT
voltage peaks (Figure 1). Measuring the Vpeak (+/-) can be achieved by this dynamic function with a sampling rate of 500 kHz (Figure 2). The
dynamic loading mode can simulate different loading conditions for most users' requirements. Its dedicated remote load sensors and control
circuits guarantee minimum waveform distortion during dynamic loading.

Master / Slave Parallel Control
When the need is for increased power, paralleling two or more loads together can be done to achieve the desired current. The 63600
provides the user with smart Master/Slave mode controls, that enables the user to program the loading currents on the Master and have them
calculated and downloaded automatically to the Slaves. With several loads working in Master/Slave mode emulating a single load unit, will
dramatically simplify the user's operation. The 63600 can be configured with USB, Ethernet, and GPIB interfaces as options for remote control
and automated testing applications.

Timing Function
The 63600 series loads include a unique timing & measurement function allowing precise time measurements in the range of 2ms to 100,000s.
This feature allows the users to set the final voltage & timeout values for battery discharge testing and other similar applications.
For example, Figure 3 shows that the 63600's internal timer can be
initiated automatically when the battery voltage falls below a preset
value. The timer will continue counting until the second preset
value is reached.
The Timing function can be used in testing battery and super
capacitor discharge, fuse and breaker protection, rise time for ATX
or D/D power supplies, and other similar applications.

Program Sequences
The 63600 series offers 100 programmable loading sequences that enable the user to simulate various real world conditions. In addition,
each module can be operated independently or synchronized so that all modules start operating at the same time while running independent
programs. Below are some examples of the most popular program sequences available.
Simulations of all kinds of real current waveforms for battery
discharge testing and other applications are possible.

SINE WAVE DYNAMIC FUNCTION
The 63600 has a unique sine wave loading current that allows the user to set the loading
current bias(I_DC), the loading sine wave(I_AC) and sine wave frequency without any external
function generator. As figure right shows CH1 is the actual loading current waveform and CH2
is the voltage waveform of the UUT. This function can be used in D2D/ATX Power supplies for
sine wave dynamic testing.
Digitizing Function
The 63600 offers a digitizing function that makes the load very convenient for recording transients in both voltage and current waveforms.
The following are the specifications of setting parameters :
SAMPLING TIME : 2µs to 40ms / R : 2µs (Setting the interval of sampling time)
SAMPLING POINT : 1 to 4096 (Setting the total sampling points)
Measurements
The 63600 series provides three operating current ranges and a built in 16-bit, precision A/D converter, achieving 0.025%+0.01%F.S.,
0.05%+0.05%F.S. and 0.1%+0.1%F.S. accuracy for voltage, current and power measurement respectively. Precise measurements like these
are ideal for testing power efficiency and other critical parameters of the UUT's. The 63600 can also measure OCP/OLP trip voltage and
current.
