Key Points of Typical Application Circuits

According to the official basic connection diagram:

Input side: Each module requires a 6.3A DC fuse (fast-blow or general fuse type) in series.

Input capacitor C1: electrolytic capacitor ≥50V/120μF, it is recommended to choose a model with low ESR and excellent temperature characteristics;When the input line impedance is high, the capacity needs to be increased.

Output side: +Vout and COM indirect positive load, -Vout and COM indirect load, COM is two-way common ground.

Ripple noise: In actual use, an external output capacitor is required to achieve the 95mVpp indicator, refer to the user manual for specific details.

VII. Product Advantages

±12V symmetrical dual-channel output: A single module can power circuits requiring positive and negative power supplies, such as operational amplifiers, analog front ends, and RS-232 interfaces, eliminating the need to combine two single-channel modules.

Fully metal-shielded on all six sides: low electromagnetic radiation, strong anti-interference capability, suitable for industrial noise environments.

9~36V ultra-wide input: compatible with 12V/ 24V industrial control bus and battery power supply system, simplified selection

-40°C low-temperature startup: Wide operating temperature range design, suitable for harsh environments such as outdoor, automotive, and industrial control applications.

1500VDC Isolation: Complete isolation between input and output, enabling safe separation of high-voltage and low-voltage sides.

1×1 inch standard package: Pin-compatible with other models in the same series, PCB layout can be reused, and the PCB layout can be replicated.

VIII. Typical Application Scenarios

Industrial control panel, PLC analog module
