Model 63600 series, 7 Innovative Designs. ( more details, please click here. )

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 behavior.

  CZ Mode

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.

Low Voltage & V-I Curve Operating Characteristics (Typical)

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.

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, this 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 users' operation. The 63600 can be configured with USB, Ethernet, and GPIB interfaces as options for remote control and automated testing applications.

  Master/Slave Parallel Control

Parallel Control:
The 63600 series loads include an 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. 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.

  Battery Discharge Testing

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. 1. Simulations of all kinds of real current waveforms for battery discharge testing and other applications are possible. (Notebook, Electric car and Electric bike) (Single output channel for UUT)

  2. Load cross regulation for ATX12V power. (Multi-output channel for UUT)
  3. Peak power cycle test of printer power (Three output channel for UUT)

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)

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. Also included in the 63600 are self-diagnostic routines and full protections against OP, OC, OT and alarm indicating OV, reverse polarity. This ensures the quality and reliability of the 63600 and provides protection of units under test.
