2 / 5 page ■ Shape, dimensions and terminal composition Weight: TBD Unit: mm Unspecified dimensional tolerance ±0.5 1) Terminal Material: Phosphor bronze Treatment: Ni base Au plating 2) Case Material: Brass Treatment: Nickel plating ■ Standard method of use ■ ON/OFF Control Output voltage can be turned ON/OFF by closing/opening between the ON/OFF terminal and -Vin terminal. Ensure that there is no chattering to the ON/OFF terminal which affects output voltage. Output residual voltage is 0.5% or less when output is OFF under ON/OFF control (at the rated input-output). As the ON/OFF terminal is pulled up to +Vin inside the power supply, pay attention to the voltage of elements (photocoupler, transistor, etc.) to switch the ON/OFF terminal. Short-circuit when ON/OFF is not controlled. Between ON/OFF terminal (5) and -Vin terminal (2) (1) Output OFF when opened (2) Output ON when short-circuited (0 - 0.4V, 1mA max.)
