The power supply ESRDS1337 Discharge Tube Power Supply is a very useful & unique
Power Supply which provides the High Voltage (10 to 500V & 0 to 80V) & Low Voltage (0
to 20V DC, 5 Amps.) along with the DIGITAL DISPLAY for Voltage & Current. It also
provides the AC Voltage selectable from 1 to 6V AC, 2 Amps. All the outputs provided are
independent of each other and can be used simultaneously.
The DC voltage 10 to 500V (adjustable) & 0 to 80V (adjustable) are displayed on the
DIGITAL DISPLAY by selecting with the help of Voltage Monitor Selector Switch.
The Low Voltage 0 to 20V, 5 Amps. DC output voltage is displayed on the DIGITAL
DISPLAY. The Voltage or Current Display is selected with the help of A/V selector switch.
The 6V AC, 2Amp. is also provided on four different Sockets, The A/C Voltage can be
selected from 1 to 6V in the step of 1V, out of these four sockets.
The 2 Amps. AC Overload Cut-Off Resettable Switch is provided in series with the AC
O/P for the overload protection. Once the AC Current exceeds the 2 Amps. The switch
will be cut off & O/P will be reduced to Zero. This switch has to be reset to reactivate the
AC Output voltage.
Operation :
1.
Select the mains input with the help of slide switch provided on the rear panel 120V
(50/60Hz) or 240V (50/60Hz) .
2.
Connect the power chord to the mains outlet after selecting the desired input.
3.
Flip the ON/OFF ( I & O) switch to the (I) ON position. The ON position of the Power
Supply is indicated by the Neon light.
WARM - UP PERIOD :
For accurate, outputs & Digital Displays of voltage & current the warm up period about
the 15 minutes is required.
