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. The 63600’s state of the art design uses DSP technology to simulate non-linear loads using an unique CZ operation mode allowing realistic loading behaviour.

The Chroma 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 Chroma 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.
