    230V ± 10%. Switch on the instrument. The power ‘On’ is indicated by lighting of displays. Operation: The Multiple Power Supply Scientech 4077 has three electrically isolated supply voltages. This permits easy series connection of output voltages. In case of series connection the maximum output voltage increases with a maximum current of 2Amp.
  • Page 13: Functional Checks

    DC output voltage should be  4.0 V, when measured on DMM. Check of maximum output current: Set the current limit knob "I maximum" to 5V maximum Short circuit the output terminals. The reading on the current display should be 2.10A Scientech Technologies Pvt. Ltd.
  • Page 14 Set the I maximum, to maximum Connect two equal loads of any value to both '+' and '-' outputs with respect to common terminal. Check the ripple and noise on DMM. It should not be more than 1mVrms in both the sections. Scientech Technologies Pvt. Ltd.
