Applications

Our ferromagnetic, air-cooled regulators provide precision control of runway lighting series circuits in medium and high intensity applications.

Features

• Proven technology for airfield lighting.
• Reliable for long life with low life cycle cost.
• Exceeds FAA performance requirements.
• Durable for various electrical vault environments.
• Versatile for medium and/or high intensity lighting.
• Self-protected from overloads and shorts of loads.
• Noise emission free.
• Air cooled - no hazardous cooling materials.
• No harmful harmonics.
• No SCRs in series power circuits.
• Predictable - no complex electronics.
• Easily maintained.
• Control circuit for remote operation of #19 AWG 10,000 ft. round-trip.
• Control circuits protected by circuit breakers, no spare fuses needed.
• Warranty for 2 years from date of shipment or 1 year from date of installation (first occurring).
