STK400-050

Specifications

Maximum Ratings at Ta = 25°C

Notes

• Use rated power supply for test unless otherwise specified.

• When measuring available time for load short-circuit and output noise voltage use transformer power supply indicated

below.

• Output noise voltage is represented by the peak value rms (VTVM) for mean reading. Use an AC stabilized power

supply (50 Hz) on the primary side to eliminate the effect of AC flicker noise.
