The Velleman VM124 is a PRE-ASSEMBLED LM317 based power supply module that provides a regulated voltage, adjustable between 1.5 and 35 volts DC with a maximum current capacity of 1 Amp.
With the LM317 regulator remarkably better ripple and regulation characteristics are given than with conventional regulators.
Current limiter and thermal overload protection are included in the IC. Supplied without heat sink.
You need to add a suitable input power source e.g. AC transformer, higher voltage DC battery, etc (see User Manual for details). The input voltage needs to be 2-3V above the required output voltage for proper operation and with a current rating sufficient for the current to be drawn.
Supplied without heatsink. You can use a heatsink like our order code HS-TO220 to increase the current rating up to a maximum of 1.5 Amps.
Also available in SELF-ASSEMBLY Electronic Kit format(Order Code K1823).Specifications
