I have an Astec DS 1500-3-001 power supply that I want to use a a stand alone PS. What pins do I need to connect to get +12v DC output with 120 VAC Input.


Mike
I take it that this is a standard power supply out of a PC (switch mode)
These are a common connection point on any brand PC
Use a DC Voltmeter to find the Ground, +5 Volt & +12 volt wires to power your 3.5 inch Hard Drive. The 2.5" Hard Drives (laptop) has only Ground (Black) & +5 Volt.

Put wrong power supply into unit


You probably blew it. It sounds like the power supply put out more voltage then needed. Also they come in AC/DC, putting AC into a DC input usually blows things, dC into an AC normally does not hurt it assuming the voltages are in range in all cases.

Micromax x225 is showing low signal


Ever looked at the power specifications of a mobile charger?? well if not, then have a peek... u will read that the output voltage is 5V DC........ the computer USB also has a voltage output of 5V DC........... any USB based electronic device needs this power to get started.... The laptop coolers u get basically work on this power from the USB... U'll notice that the USB ports have 4 terminals.... the extreme outer side are the POWER terminals +ve and -ve..... the middle 2 are the BUS lines IN and OUT.... a BUS is something electric conductive that allows the flow of 0's and 1's or rather high and low voltages to pass(Basic IT theory).... so this 5V DC can be used for doing anything; charging the mobile phone battery to lighting up entire rooms with LED's, making laptop coolers, etc......... Every mobile phone which has the USB connectivity option gets charged when plugged in... so sometimes even if u dont have the Mobile charger dont panic, find a computer and plug in the USB... not only micromax x225 mobile but, there are almost 80% mobiles which charge by connecting it to pc. Only nokia phones don't get charged. it is a good feature don't worry

I have an Electrovoice MA-1212 That when I hook it up and power on all I get is a constant low frequency Hum. Checked the wiring and speakers on another amp and eliminated them? Any suggestions?


WIth the speakers disconnected, measure the terminals using a DC voltmeter. I suspect that there is DC voltage there where there should be 0V. If that is the case, the output transistors are shorted and need to be replaced.
