POWER SUPPLY 9V - 1A - SMPS

Resonance Power Supply Module, Very Compact, High Efficiency

• Input: 90 V - 260 V AC / 50 or 60 Hz

• Output: 9 V - 1 A constant load - 3 A peak

• Completely silent

• Weight & size are negligible

• Minimal heat generation

• No induction or radiation

• DC heating of tubes: eliminates any 50 Hz noise or harmonics and simplifies ground circuits

• Precise output voltage adjustment between 8 V and 9.8 V minimum

• Soft-start for smooth power-up

• Voltage regulation accurate to 0.01V regardless of mains input (90 V to 260 V) and load (up to 2 A)

This module replaces a heating transformer, rectification system, and regulation electronics in a very small space.

Connections are simple with 5 screw terminals:

• 2 "AC" terminals for mains input,
• 1 "FG" (Frame Ground) terminal for shielding connection to ground or earth,
• 2 output terminals: "G" (negative) and "V" (positive), delivering 9V output.

The device is protected against electrical and thermal overloads, short circuits, and overvoltage. An integrated mains filter is included.
