2.1.1 External Power Supply

The ASD2-EVAL-001 Evaluation Board operates on +15 VDC. An external power supply of +15 VDC is provided at connector J2 on pin 1 and pin 2 with respect to pin 9 and pin 10 (GND). The current consumption in the quiescent stage without applying any pulses is approximately 60 mA, 65 mA in double pulse mode, and 80 mA in OSC mode. A supply of +15 VDC can be provided at the test point (terminal). Further, +5 VDC is generated on-board using a regulator U5 IC. See the following figure.

The external power supply of +15 VDC is sourced from a low-voltage variable DC power supply (for example, Dual Channel DC Power Supply Adjustable, Part Number 72-10500, Make TENMA).
