5.2 Fitur canggih
5.2.1 CC & CV Priority Function
The CC (Constant Current) and CV (Constant Voltage) priority function helps to solve severe problems in long-term testing. You can select the CV priority mode to obtain a faster voltage rising speed, or choose CC priority mode to output current without overshoot. This function is beneficial for applications such as laser testing, IC testing, charge and discharge testing, power transient simulation, and characterization of automotive electronics.
5.2.2 Web Aksés Server
The IT-M3100D series has a built-in Web server. You can monitor and control it through your web browser. After the IT-M3100D is connected via LAN interface, enter the IP address of the power supply in the browser to access the web interface. This allows remote control and configuration of LAN parameters.
5.2.3 Synchronism (Link) Function
The IT-M3100D supports synchronization functionality for both single and multi-channel power supply systems. There are three synchronization modes: On/Off, Track, and Duplicate. These modes allow parameters to be automatically replicated or proportionally synced to other power supplies in the link. The ON/OFF function utilizes the ON/OFF delay function in the menu for synchronous or sequential power-on operations.
5.2.4 Multi-Protection Functions
The IT-M3100D dual-channel DC power supply includes various protection functions to safeguard the device and the connected load:
- OVP (Leuwih Voltage panyalindungan): Protects the load from excessive voltage.
- OCP (Leuwih Perlindungan Ayeuna): Protects the load from excessive current.
- OPP (Protéksi Daya Leuwih): Protects the power supply from excessive power output.
- U-Max/U-Min (Under/Over Voltage Limit): Sets upper and lower voltage wates.
- Sense (Remote Sense): Compensates pikeun voltage drop in the load wires.
- Foldback: The output turns off when the power CV/CC is switched, protecting sensitive loads from overshoot.

- Kalibrasi: Periodic calibration by qualified service personnel is recommended to maintain accuracy.
7. Cara ngungkulan
If you encounter issues with your IT-M3100D series power supply, refer to the following common problems and solutions:
| Masalah | Mungkin Cukang lantaranana | Solusi |
|---|---|---|
| Teu aya daya/Unit teu hurung | Power cord not connected, power outlet faulty, internal fuse blown. | Check power cord connection. Test outlet with another device. If fuse is suspected, contact support. |
| Teu aya kaluaran voltage/ayeuna | Output disabled, OVP/OCP/OPP triggered, load disconnected or faulty. | Ensure output is enabled. Check protection settings and reset if necessary. Verify load connection and integrity. |
| Kaluaran teu stabil | Poor load connection, remote sense not properly configured, external interference. | Check load wiring for loose connections. Ensure remote sense is correctly wired if used. Isolate from strong electromagnetic fields. |
| Overheating | Blocked ventilation, operating in high ambient temperature, excessive load. | Ensure ventilation openings are clear. Operate within specified ambient temperature range. Reduce load if continuously overheating. |
