Each load module is designed with state-of-the-art technology and connects all suer power MOSFET devices in parallel to insure high accuracy load control with a minimum drift of less than 0. In change of modes the module s input is momentarily disabled before a new mode is enabled. When local operation is in effect, you can select a channel, and use the display as well as keypad on the front panel to control the Load. The A load modules operate in constant current, constant voltage, constant power or constant resistance to satisfy a wide range of test requirements.

Slew rate determines the rate at which Load level changes from one load level state to another. The front panel keypad and display allow manual control of individual module when Load is used in bench test applications. In CR mode it is equivalent to the programming of the minimum resistance for the present resistance range. The typical temperature coefficient is ppm. This manual offers important information and suggestions with respect to installation, More information.
It fits for testing multiple output switch power supply. Notice The potential of Vsense red connector must be higher than 634 of Vsense black connector Parallel Connections Figure usrr how modules can be paralleled for increased power dissipation. Complain wrong Brand wrong Model non readable. Here Load means the electronic load modules of Chroma series while Mainframe theelectronic load mainframes. The unit contains no user replaceable parts.
The system is configured by plugging the user selectable load modules into the system mainframe. Basic Calibration Before executing calibration, you need to. The loading waveform is programmable in slew rates, load levels, duration and conducting voltage.
DC Electronic Load | Chroma ATE Inc.
When programmed data are over the boundary, Mainframe will set maximum or minimum level for the Load module. Keep all packing materials in case that the Load or the Mainframe has to be returned.
The differences 634 in input voltage, load current, and power ratings. The overtemperature OT and temperature error TE status register bits are set when the OT condition occurs, nanual will remain set till they are reset.
Because of the limit, the actual transition time is longer than the expected time based on the slew rate. The load sink current of CR mode is proportioned to the input voltage through a double pole RC filter. Unlike conventional supplies with fixed output ratings. Voltage and current measurements are performed with a bit resolution of full-scale ratings. However, you must install the electronic Load in a location that has enough space at the top, four sides, and the rear of the unit for adequate air flowing through and escaping from the back.
Therefore, both minimum transition time and slew rate must be considered in the determination of actual transition time. Figure also illustrates a typical setup for remote sensing operation. FUSES Only fuses with the required rated current, voltage, and specified type normal blow, time delay, etc. Home About Us Contact Us.
Operation & Programming
Transportation to the factory or service center is to be prepaid by purchaser. The user can use multiple load modules independently to test multi- output power supplies, or parallel them for high power testing applications.
If your application requires a greater power or current capacity than one module can provide, you have to connect load modules in parallel in CC or CR mode. Lock the module in place by use of the screwdriver see Figure Documentation Brake module AX Please read this document carefully before installing and commissioning the brake module!
At this moment channel 2 and 4 are empty Mainframe has only four channels 1, 2, 3, 4. The A series offers 8 types of modular loads with power ranging from watts to 1, watts, current from 0.
Shipment should not be made without prior authorization by Chroma. Chroma’s obligation under this warranty is limited solely to repairing any such instrument, which in Chroma’s sole opinion proves to be defective within the scope of the warranty when returned to the factory or to an authorized service center. All Chroma instruments are warranted against defects in material and workmanship for a. The user can perform on line voltage measurements and adjustments or simulate short circuit test using the user friendly keypad on the front panel.
Daker DK 1, 2, 3 kva. An error will occur when data are over the maximum or minimum value Constant Current Mode Figure Constant Current Mode In CC mode, the Load will sink a current in accordance with the programmed value regardless of input voltage.
Nothing contained herein shall More information. The parameters in current, resistance or voltage mode can be programmed simply as the mode is presently selected. All fields are required. In addition to this manual, be sure that the following items have also been received with your Mainframe and Load.
Check the Load and Mainframe connection when an error occurs. Minimum input resistance allows load to sink high current even with low input voltage 1 V. Up to 8 channels for one Mainframe.
