Chroma 63209

 Chroma 63209 Programmable DC Electronic Load      The high power rating, parallel and synchronization capabilities make the Chroma 63209 DC electronic load especially well-suited for high power applications such as switch-mode rectifiers and for discharging batteries packs and fuel cells. With front LCD displays and rotary knob, the Chroma 63209 loads offer versatile bench top operation. Complex waveforms can also be created by driving the loads from an analog programming source.    The Chroma 63209 programmable DC loads provide constant cur, constant resistance, constant voltage and constant power modes. For low voltage/high cur applications, the Chroma 63209 electronic DC load is available with a low voltage mode, which provides ultra-low voltage operation and in many cases can compensate for large voltage loss in the input wiring. A cur closed loop design connecting all power MOSFET devices in parallel insures high accuracy load control with minimal drift (less than 0.15% of the cur setting).  The load can short a DC power source or any power supply that has a built in cur limit function and measure its short circuit cur so that users can verify if the UUT cur limit is functional. Specifications for the Chroma 63209 High Power DC Electronic load include:
