SMPS Module HY15-12 Audio Tone Control Split Power Supply +/- 15Vdc(2A) + Auxiliary fixed +12Vdc (1A) for DIY modular build of Music Gadgets (Green)

Description

The HY15-12 SMPS  (Switch Mode Power Supply)  is the modern approach of supplying DC power to our Audio Tone Control board  (like the product:   Baxandall DIY Audio Tone Control with Bass, Mid, Treble Pure Analog Tone Control (PATC)  making it space effective, economical, lightweight and efficient use of power.

The HY15-12 SMPS Module will replace the old traditional Transformer + Rectifier + Capacitance + Passive Regulators to generate a DC signal of +/-15Vdc  from the household 220Vac power.  The old solution is bulky, costly and heavy because of the transformer which is metal parts.

 

Applications:

1. Audio Tone Control requiring split power supply of +/-12Vd ~  +/-22Vdc
2. Any other electronic board that requires split power supply

 

Specifications :

Input Ac Voltage              :   100 ~250Vac / 50~60 Hz

Max Voltage Output       :   Tone Control      :  +/-15Vdc @ 2 Amp  (split supply +/-)

adjustment :  +/- 13.8 ~ 17.8 Vdc

Auxiliary (Aux)   :  Fixed +12 Vdc @ 1 Amp    (single +)

Aux GND is isolated from +/-15Vdc GND

Max Power  Output        :   72W

Ripple Voltage                   :  Tone Control       :  < 20mVrms

Auxiliary (Aux)   : < 30mVrms

PCB                                        :  FR4 – 2 sided  (Green), 1.6 mm

PCB Size                               :  100 x 67 x 27 mm

Safety :

Standard                              :  EN55022 Electromagnetic Compatibility / EN60950 Safety

Hi-Pot Test                          :  Input to output 1800VAC 5 seconds 5mA

 

 

Interfaces Definition / Function:

1. AC input

Input the AC voltage

2. Output Voltage : Tone Control

Supply +/-15 Vdc to the Tone Control board

3. Output Voltage : Auxiliary Circuit

Supply +/- 12Vdc to other circuit   (please note that the maximum current you may get from

supply is 0.75Amp (750mAmp) to include safety factor, DO NOT maximized the 1Amp output

current).

 

DIY  (Do-It-Yourself)  Build of Tone Control Music Gadgets  :

1. This is a SMPS Power Supply which replaces the Transformer, rectifier and smoothing capacitors + Regulator circuits in a traditional Power Amplifier Power Supply system
2. The maximum voltage of the Tone Control should be known, maximum is +/-15Vdc
3. This Auxiliary supply is fixed +12Vdc, you may allowed to use 750mAmp of dc current to supply other circuits like Relay,  MCU,  LEDs and etc.    If you need to use it for small fan,  make it sure that it do not draw more than 750mAmp.  The maximum current is 1.0 Ampere but put a safety margin to use only 750mamp or 0.75Amp.

 

 

CAUTION:

This SMPS Module carry lethal 220~240Vac AC voltage –  Electrical safety should be observed.   If this is your first time to work with 220 ~240Vac with SMPS,  you may consult a professional electronics person and guide you to use this product.   Never touch any part of the SMPS module when it is connected to the 220Vac power.
