Hello everybody,
by no means, I'm an electronics "guru" quite the reverse.
I will appreciate if someone explains me in the simplest terms how to wire Hypex NCAS500MP H-Bus connector J7.
I will attach the amplifier's pdf.
This amplifier has two power supplies, a standby supply and the main power supply (PS).
Would like to avoid damaging the amplifier with faulty wiring, this is why asking for very much needed help.
The connector looks like this:
J7.1 Output VAUX Positive auxiliary supply
J7.2 Output VAUX Negative auxiliary supply
J7.3 Output VOUT,STANDBY Regulated standby supply
J7.4 - GND Ground
J7.5 n.c. SDA (I2C) Not connected
J7.6 n.c. SCL (I2C) Not connected
J7.7 Output DC Error DC Offset detected, power supply disabled.
J7.8 Output Power Good Power supply stable indicator
J7.9 Input PS Enable Power supply enable
J7.10 Reserved Reserved Not connected
Questions I would like to ask for help to answer :
1. To activate the main power supply (PS) and power the amplifier. Is it J7.3 to J7.9 pins must be connected(wired together) ?
2. A standby supply. If I have understood correctly, can be used in external power supply 3.3VDc to 12VDc. This method is favoured by Hypex .
Is it J7.1 and J7.2 pins are used for that ?
Thank you in advance
