Currently out of stock! 9 volt 150 ma  DC Power Supply for use with BK-100 & BK-200 Series Kits. Power supply is 9 volts DC @ 150 ma current draw. The voltage may be higher at lower current draw. The BK- 100 & BK-200 series kits have in circuit regulators to regulate input voltage to 5 volts. Output Plug must be removed for use with BK kits! Supplied with bare leads

If using a higher output, such as the driver circuit for multiple LEDs, with a BK-100 or BK- 200, the PS-681 or PS-12700 power supply is recomended! See PS-681 for more details. 

A Note on this Wall Transformer if not using with a BK kit:  This D.C. Wall Transformers is not regulated and provides a specified voltage at a specified load. If the load is lower than specified, the voltage will be higher then specified. With a higher load, the voltage will drop below that specified. The BK- 100 & BK-200 series kits have in circuit regulators to regulate input voltage to a fixed 5 volts, so if using on other than a BK kit, you should be aware of the voltage variations.
