DLM1610D · DYNAMIC LOAD MODULE · ELECTRONIC EQUIPMENT
INTRODUCTION
The Dynamic Load Module (DLM) is electronic equipment that behaves as a controlled DC load. Though this module has been developed for the automotive sector to help in the development, validation and manufacturing departments, it is also suitable for other markets where load current should be characterized.
The DLM1610D is based on internal power semiconductors to set the load operating point. Thus, any load current profile can be set via CAN message with high accuracy and at the minimum switching time.
Each module has a unique serial number (SN) for addressing purposes. This SN can be requested under a CAN command, and it cannot be updated by the user. Each DLM1610D will be externally identified with this serial number codified in a bar code label.
The main application areas in any industry are:
• Development. As a configurable load, it saves time when reconfiguring the load panels that have expired with the project.
• Validation. Easy reusability of load panels for Device Under Test (DUT) life cycle verification under power stress conditions.
• EOL testing. Test equipment simplification in regard to cost, size and complexity due to the possibility to set the required output current for the test.
APPLICATIONS
Automotive. Development and testing of electronics devices that control any DC load. Applications in development electronics, stress testing and EOL testing.
• Power Supplies and UPS. Validation of power supply and UPS in any of its operating modes, such as constant current or constant voltage. Plus, it facilitates the validation of the product by stress, testing it with fast switch random current power delivery.
• Photovoltaic panel strings. Possibility to characterize and overstress the PV panels and determine their I/V function.
• Batteries. Necessary for the development of the algorithms required to test and characterize the batteries, such as:
1. Charge rate (CR)
2. Discharge rate (DR)
3. State of charge (SOC)
4. State of health (SOH)
5. Depth of discharge (DoD)
