More Frequently Asked Hatch Transformer Questions

What should I check if the transformer does not seem to be working?
(A) Please make certain that the black and white input wires (primary side) of the low voltage transformer are connected to the power line (120 volts or 277 volts) and that the two red output wires (secondary side) of the low voltage transformer are connected to the low voltage light source (12 volts or 24 volts). Most failures occur as a result of reverse or improper wiring.
(B) Check the filament of the lamp to see if is burned out. (Remember the glass envelope of a halogen lamp should NOT be touched by bare hands because the natural oil from your hands will cause the lamp to burn out prematurely.)
(C) Check the connection somewhere between the output wires of the transformer (red wires) and the lamp. The transformer has a sophisticated short circuit/overload protection system. If it senses a short or a bad connection or too many lamps (ie: too much wattage) it wil cause problems. Check all the connections for tightness, corrosion, arcing etc. If all are tight and clean and you do not have more than the maximum wattage of lamps on the system, then look at the lampholder itself. Make sure the contacts in the lampholder where the lamps plug in are still tight and do not show signs of carbon buildup or arcing.
Can Hatch electronic transformers be remote mounted?
Yes, they can be remote mounted up to 10 feet, after 10 feet there is a voltage drop of approximately .07 volts per foot.
Why does my voltmeter read "0" when testing Hatch transformer, does this mean the unit is bad?
No, some Hatch electronic transformers feature "Demand Circuit Design". The transformer will not produce voltage unless a lamp with at least the minimum wattage required is connected to it.
Will Hatch transformer or ballast operate at 50Hz or 60Hz?
Why is there a delay when I turn a lamp on using Hatch transformer?
Many models of Hatch low-voltage electronic transformers utilize a soft start circuitry to maximize lamp life. The soft start circuit ramps up the lamp filament voltage slowly when the lamp is cold.
Why do I measure very low voltage on the lamp even though the light output looks OK? Shouldn't it be about 11.5V?
You must use a digital volt meter capable of reading 25KHz or higher waveforms, we suggest a Fluke Model 5220A or equivalent.
What is the "blue" loop on your VS12-60WD and VS12-75WD transformers for?
This wire is only for OEM type applications. It is used to attach a 1 meg ohm linear taper potentiometer for dimming via a potentiometer. You do not have to use the blue loop to make the unit work, it is only there if you want to use a potentiometer to dim your fixture (example: Desk top lamp).
