6-Place Lampchangers

Our lampchangers are appreciated by our customers worldwide for design simplicity, reliability and lamp positioning accuracy and consistency.

• 6 Lamp Capacity S-8, S-11 and halogen marine signal lamps with Pr30s prefocused collar
• Uses rotary solenoid which is more reliable than motors and does not require any gears
• Accurate, Consistent Lamp Positioning within .031 inch (0.8mm) of true center
• Low Contact Drop
• No Light Shadowing 52° Down From Horizontal of the Lamp Filament
• Gold Plated Contacts
• Large, Color Coded Terminals
• Available With Solenoid for 6 or 12 Volt Systems
• Can be mounted in any position
• Low Cost
  

We offer the following models:

2086A, 2086B Our basic model - It is designed to operate with any solid-state marine flasher which can provide filament failure sensing and voltage pulses to actuate the rotary solenoid. The rotary solenoid indexes the lamp turret by a spring-wound ratchet mechanism. This type of mechanism positions a new lamp into place quickly, accurately and consistently.

Meets or exceeds the requirements of U.S. Coast Guard Specification numbers 195 (2086A) and 478 (2086B) including vibration test at 5-G's, shock test at 40 G's, salt spray and immersion.

Factory Mutual (FM) approved for use in Class I, Division II Groups C & D hazardous locations when used with FM approved CR Flasher in an FM approved lantern.

MATERIALS

• Gold Plated Contacts
• Terminal Connectors - Brass with Tin Electroplate
• Terminal Screws - Stainless
• Die Cast Alumimum Frame with Polyester Powder Coat Finish
• Turret - Injection Molded High Strength Plastic

We also offer the following additional Lamp Changer Models

2086APS Position Sensing Lamp Changers (also available in our other models). Position Sensing Circuit senses when the lamp changer is in the last two positions to remind the user to replace lamps. This function is accomplished by creating a closed circuit through two additional terminals when the lamp turret reaches the designated position in its rotation. This is accomplished by reed switch on the lamp changer frame and with magnets embedded in the turret - normally the last two positions. (More positions can be sensed by special order). These lampchanger terminals can be connected to an indicator lamp, buzzer, etc.

2086AC/DC - Self-Switching Lamp Changers. This model operates with an input voltage of either 12 VDC or 12 VAC. It is designed to detect the absence of light from the lamp when power is applied to the lamp. If no light is sensed then the circuit will place a new lamp into position during periods of low ambient lighting. We plan to introduce a model where we sense lamp current rather than light. Surface Mount Technology.

2086FL - Economical Marine Flashers with Lampchangers. It offers simple flash, or fixed light as well as self-switching function. Choice between simple flash and fixed function is made by switch. Flash and eclipse lengths can be adjusted by potentiometers. Surface Mount Technology.

2086BLR - Six Place Lampchangers. We developed the 2086BLR Lampchanger under contract with the U.S. Coast Guard to meet Specification G-SEC-478 which includes a requirement that the resistance through the lamp circuit not exceed 0.010 Ohms, after extensive heat testing when running a 110 Watt halogen marine signal lamp. The "LR" in "BLR" stands for low resistance.

In order to achieve this low resistance, significant material and assembly changes were made to the 2086BLR lampchanger from the 2086B version, which include the following:

1. Elimination of one of the two Spring Contacts (between circuit board and turret) and replaced it with 16 gauge tinned copper stranded wire. This cable is threaded through the turret. A high temperature engineered plastic is used as a pivot with stainless steel tube to hold the turret instead of the solid stainless steel pivot used on our other lampchangers.
2. The other Spring Contact is doubled up to increase contact pressure. A higher conductivity spring material is used.
3. All gold plated brass parts have been replaced with gold plated copper.
4. The three colored terminals have copper inserts instead of brass.
5. Six contact plates on top of the lamp turret positions have an inlaid silver/nickel contact strip running the full length of the part through the tab overhang. This is the best moving contact material available.
6. There are six terminal resistors instead of only one and they are connected by 20 gauge solid copper tinned wire to create a parallel electrical power path to the back-up ring.
7. A heat baffle is mounted at top of the lampchanger to shield the top turret ratchet tooth from lamp heat. All other specifications are similar to the 2086B version of our lampchanger.
