    Operation Overview Resistance can be programmed in either of low range or high range by the RANGE key. The low range is used for input voltage in low voltage range while the high range is for the input voltage over low voltage range. The current range of CR mode is high range. There are two resistance levels (A or B) for CR function as static CC mode.

    3.5.5 Load Surge Capability Chroma’s 63200 Series DC Loads provide a unique load surge simulation capability, which allows users to overdrive the loads up to 2.7 times their rated power for short periods. This feature is ideal when the average power require by the UUT is low compared to short-term peak power demands.

  • Page 59: Slew Rate & Minimum Transient Time

    Operation Overview Slew Rate & Minimum Transient Time Slew rate is defined as the change in current over time. A programmable slew rate allows a controlled transition from one load setting to another to minimize induced voltage drops on inductive power wiring, or to control induced transients on a test device. If the transient from one setting to another is large, the actual transient time can be calculated by dividing the current transition by the slew rate.

    Please be noted that turning on the short circuit may cause loading too much current to trig protection circuit to turn off the Load. The 63200 series have a TTL signal from RS-485 pin 6 for your application to control the external short relay. TTL indicates high/low when the short key is set on/off.

  • Page 61: Load On/Off

    Operation Overview 3.10 Load On/Off A module’s input can be toggled on/off through the blue LOAD ON/OFF key on the front panel, or the remote control. The on/off change for input is done according to the slew rate. Turning off the load does not affect the programmed setting. The load will return to the previous programmed values when the Load is turned on again.
