To guarantee the safe use of the power supply, the total
maximum voltage at each terminal must not exceed 240V
with respect to ground.
• 2x 60V/2A = 120V/2A
• 2x 120V/1A= 240V/1A
• 2x 8V/15A = 16V/15A

• 2x 60V/2A = 60V/4A
• 2x 120V/1 = 120V/2A
• 2x 8V/15A =8V/30A
Only output channels with equivalent voltage and current
ratings may be connected in series or in parallel to prevent that
the channel with the lowest ratings will be damaged.
