Page 43: Installing The Modules
Use standard anti-static work practices when you handle and install modules. Avoid touching the connector and the circuit board. Chroma 63600-5, 63601-5 Mainframe has room for five single-width Loads (63610-80-20, 63630-80-60, 63630-600-15, 63640-80-80, 63640-150-60); Loads can be combined in the Mainframe in any order.
Page 44 Programmable DC Electronic Load 63600 Series Operation & Programming Manual Figure 2-2 Installing Modules in the Electronic Load WARNING If the Mainframe is not installed with all modules, the empty slot must be covered with the panel cover for safety and airflow. To unplug it, lift up the switch between the load connectors, using load connectors to help you draw the module out of the mainframe.
Page 45: Channel Number
The channel number of the Load is determined by the module location in the Mainframe starting from the farthest left slot. As some Load (63610-80-20) has two channels in one module, channel 1 and 2 are always on the farthest left slot of the Mainframe, and channel 9 and 10 on the farthest right.

Programmable DC Electronic Load 63600 Series Operation & Programming Manual Most of the functions that perform remotely can be done locally too at the Load Module front panel. The keypads on the Mainframe can perform simple functions like specific setting, data lock operation, save/recall setting.
Page 59 Operation Overview In CC mode, the Load will sink a current in accordance with the programmed value MODE regardless of the input voltage. To enter into the CC mode, press the key a few times until the VFD displays CC mode. Current Ranges (Low, Middle, High) Current can be programmed in any of the three ranges, low range, middle range and high range.
Page 60 Programmable DC Electronic Load 63600 Series Operation & Programming Manual Dynamic Load Mode There are two Operation Modes for dynamic load: Dynamic load mode and Dynamic load DYNA frequency sweep mode. Press to select Dynamic load or Dynamic load frequency sweep mode.
Page 61 Operation Overview Dynamic Load Frequency Sweep Mode Figure 3-12 CC dynamic Frequency Sweep Current Waveform The Load offers a unique CC dynamic frequency sweep with variable frequency to find the worst case UUT voltage. Frequency Sweep Function operation enables you to program two load levels (Load1 and Load2), Start frequency, End frequency, Step frequency, Dwell time, duty, slew rate (Rise and Fall).
Page 62: Constant Resistance Mode
Programmable DC Electronic Load 63600 Series Operation & Programming Manual 3.5.2 Constant Resistance Mode Figure 3-13 Constant Resistance Mode In CR mode, the Load will sink a current linearly proportional to the input voltage in accordance with the programmed resistance. This mode is operated under the F/W calculation.
Page 63: Constant Voltage Mode
Operation Overview 3.5.3 Constant Voltage Mode Figure 3-14 Constant Voltage Mode In CV mode the Load will sink current to control the voltage source in programmed value. This mode is operated under the F/W calculation. That is, take the voltage setting, divide the measured output current of UUT’s CC mode and get the suitable resistance as the equivalent resistance of the Cells.

The method each channel loads On/Off can be controlled by the ALL RUN setting. The loading of channels with the ALL RUN function turned on, can be controlled via other channels with ALL RUN settings turned on.
Page 66: Slew Rate & Minimum Transient Time
Programmable DC Electronic Load 63600 Series Operation & Programming Manual 3.8 Slew Rate & Minimum Transient Time Slew rate is defined by the change in current over time. A programmable slew rate allows a controlled transition from one load setting to another to minimize the induced voltage drops on inductive power wiring, or control the induced transients on a test device.
Page 67 Operation Overview Figure 3-17 Start Sinking Current (Von Non-Latch) Figure 3-18 Stop Sinking Current (Von Non-Latch) In the battery discharge timing measuring mode, you may set the conducting voltage Voff to avoid repeatedly start sinking and stop sinking current when the UUT output voltage is repeatedly up and down near the Von voltage.
