Mainframe for 1 Load Module
Chroma's 63600 Series DC Electronic Loads are designed for testing multi-output AC/DC power supply, DC/DC converter, charger, battery, adapter and power electronic components. The 63600 Series is well-suited for application in areas such as research and development, production, and incoming inspection. The 63600 Series' state of the art design uses DSP technology to simulate non-linear loads using a unique CZ operation mode allowing realistic loading behavior.

The 63600 Series can draw its rated current under very low voltage (0.8V typical). This unique feature guarantees the best loading performance to a low voltage power supply. The 63600 series can simulate a wide range of dynamic loading applications, with programmable load levels, slew rates, duration and conducting voltage. The 63600 series also have dynamic sweep function to meet the test requirements of ATX power.

Furthermore, up to 100 sets of seetups can be stored in EEPROM and recalled instantly for automated testing application. Real time measurement of voltage and current is integrated into each 63600 load module using a 16-bit, measurement circuit with three ranges of operation. The user can perform online voltage measurements and adjustments, or simulate short circuit test using the simple keypad on the front panel.

Model 63600 series Innovative Designs
New generation 63600 series DC Electronic Load provides innovative Dynamic Sweep mode with Vpk measurements. Dynamic mode can be run independently on each module or in parallel for high power loading. Also provided are three measurement ranges for precise voltage and current measurements making it ideal for Energy Star testing requirements. 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 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.

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 test using the simple keypad on the front panel. The 63600 also offers an unique dynamic frequency sweep with variable frequencies up to 50kHz ideal for use in finding the worst case UUT voltage peaks (Figure 1). Measuring the Vpeak (+/-) can be achieved by using this dynamic function and 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.
