230VAC OPERATION
Your DA is wired for 115VAC, 50/60Hz operation unless otherwise requested at time of
order. It can be easily modified for 230VAC operation by removing the power transformer
primary jumpers W1&W3 and inserting a jumper wire in position W2. Different types of
attachment plugs or line cords may be required for connection to alternate supply
voltages.
MAINTENANCE
Power supply voltages are regulated by A1 and A2 to +15 and -15VDC respectively. IC
output DC voltages under no signal; shorted input conditions should remain within
0.1VDC of ground. A greater deviation is an indicator of IC or circuit problems.
Inputs and outputs are susceptible to high common mode and differential AC and DC
voltages fed from external devices or appearing on ground
UL LISTING
The DA206 and DA412 are listed by Underwriter Laboratories as "Listed Professional
