TUNGSTEN-Halogen Light Controllers
MERCRON’s Tungsten Light Controllers regulate the tungsten light-source with a high-frequency, sinusoidal waveform, reducing both start-up shock and long-term filament erosion, resulting in a 50%-to-100% INCREASE in usable lamp life.

Tungsten / Halogen Considerations:
Facts:
The Tungsten / Halogen light-source is a long-standing, incandescent lamp, made desirable for Machine Vision applications by MERCRON, since it -
- Main source of infrared light
- Ideal point sources for fiber optic applications, to mention only one
- When MERCRON's Tungsten Controller is not satisfied with the light output, the All's Well Signal will alert the operator, eliminating incalculable false rejects, and unnecessary downtime

MERCRON-regulated TUNGSTEN Lamps: Before & AFTER
Any light-sources has its pros and cons.
The most appropriate lamp is determined by several factors:
- color of target
- background color
- color sensitivity of both the detector and the camera
- color temperature of the lamp itself
Regardless, MERCRON allows the System Designer to capitalize upon its positives, and goes a long way to eliminate its negatives.
- Small and simple
- Continuous spectral output
- Perfect for small target illuminations and fiber-optic bundles
- Requires extra filtering
- Doesn't have much blue output
- High levels of infrared
- Non-linear correlation of color temperature and power levels
- Erratic light-output in vision applications (see below)*
- Ordinary short lamp life (see below)*
Tungsten Light Controllers
As long as the lamps are connected in series, MERCRON’s Light controllers can regulate any combination of lamps that equal the light controller’s model number, encoded to indicate total wattage and voltage.
For example, a TXC300 will regulate either:
- 1 x 300W / 72V lamp
- 3 x 100W / 24V lamps
- 4 x 75W / 18V lamps
- 6 x 50W / 12V lamps
- 12 x 24W / 6V lamps
MERCRON’s Light controllers are voltage tolerant. A 300-watt lamp load could operate over a range of 60-to-84 volts; e.g., six 50W/10V lamps could be used instead of six 50W/12V lamps. (There is some tolerance on total wattage as well).
Y-models - which include onboard power factor correction - are generally required when multiple lamp controllers are used in a single installation, and/or for operation in Europe. Their model number’s prefix will be TY.
When ordering, be sure to specify correct version: 120 VAC or 230 VAC. MERCRON will confirm the prefix of the correct model number.
