Product Overview
MDZZZ-XXXSYYYY series products are specially designed for on-board power supply system, in order to guarantee the reliability and stability of the product, it is necessary to isolate the voltage of the input and output power supply in the
MD labeled DC Modular Power Supply.
- ZZZ stands for 030-900, representing the 3.3V-9V/DC input voltage range.
- XXX stands for 033-240, which represents an output voltage of 3.3V-24V/DC.
- S is used as a separator symbol between voltage and current.
- YYYY is labeled with output current 0042-0303, which represents 42mA-303mA.
The product is mainly suitable for:
1. Where the voltage of the input power supply is relatively stable (voltage variation range ±10%Vin);
2. Isolation is required between input and output (isolation voltage ≤1500VDC);
3. High requirements for output voltage stability and output ripple noise.
