The PPS-101 is a tiny, convenient dual power supply that provides the most frequently needed power supply voltages for circuit prototype board
development. The output is a pair of isolated adjustable, tracking supplies that can provide currents over 200 milliamperes on each output.
The two outputs can be tied together so that one supply provides positive and the other provides negative voltage. This is a common requirement for dual supply devices such as operational amplifiers. Alternatively, the two supplies can be stacked to double the output voltage or parallelled (with isolating diodes) to double the output current.
The high efficiency switching design eliminates the need for heavy, bulky heatsinks.
The PSM-101 uses an AC adaptor so the bulk of the power supply is away from the working area. The PSM-101 supply itself can plug directly into a prototype circuit board, leaving the workspace uncluttered by power supply cables. For additional convenience, the input and output voltages are also available at screw terminals.
An ‘Output Control’ button with indicator LED enables and disables both outputs, allowing one to disable power to the circuit under test while working on it.
The main output is regulated for constant output voltage up to the maximum output current. The secondary output tracks the main output with regulation of about 10% over the full output current range. Both outputs are current limited with LED indicators. The output can adjusted over a voltage range of zero to at least 12 volts. The PSM-101 is electrically quiet, with dual
common-mode noise filters. The output noise voltage is only 3mV peak-peak, which makes the supply well suited for audio and instrument circuit applications.
Combined with a digital voltmeter and other Syscomp instruments such as the CGR-201 CircuitGear oscilloscope, the PSM-101 creates the core of a portable, low-cost analog and digital electronics laboratory.
Universal AC adapter included.
