  • Fact: The load on the needle changes as it goes from above the skin
  • (when you step on the foot switch) to penetrating as you enter the skin
  • and as you move around. you can hear the difference.
  • Instek responds faster adjusting the current keeping the speed
  • More constant under different pressures.
  • Instek has the lowest fluctuation -- check the figures below.
    Others don't publish their figures - they want to hide them!
    When someone says they design and make a power supply,
    you can bet there is no verifiable standards.
     ISO-9001 Certified Manufacturer of Electronic Equipment.

    Gone are the days of garage and back room manufacture.
  • It takes sophisticated facilities and sophisticated circuitry to produce
    high-end power supplies that are certified to work both in the USA
    and are awarded European Union Certified with Authentic Labels as
    well as RoHS Compliant Standards.

It takes sophisticated circuitry
not a "minimum of wires "
 to make a great power supply.
(That's why it weighs 10 lbs.)

If you take the cover off and
only see 3 or 4 things in your chassis,
you cannot expect high performance.

20 Input/Output Connector With 19 Master-Slave switch selection, permits from the Master Unit (Serial or Parallel) output connected to Slave unit (Ser. or Par.) Inputs.
For Tattoo, Use the
Jumper (Supplied)
located in the same Bag
as Instruction Booklet.

Set-Up Instructions
For Combo FS/CC
Jumper - metal connector in the shape of an "H"  supplied in the same bag as the manufacturer's detailed specification booklet.
The "Jumper" is used to connect the Negative Output terminal # 9 and the Ground Terminal # 8(-) together.   This enables the use of a 2-prong Double-Banana plug to plug into # 7(+) and # 8(GND) output terminals.
Notice about international electric compatibilities.
This Electronic equipment rated for 110-120 Volt  and  220-240Volts
You will need to change the plug on the power cord
if your country does not use American standard 3 prong plug.
