AC Power Mains Impulse

Model 330 Series are structural protection assemblies that offers transient and overvoltage protection throughout the house or structure to items connected on the AC power lines connected through circuit breaker protection to the main incoming electrical panel, this unit requires only simple wire connections done in about 5 minutes time.

Once installed units provide diversion to incoming high voltage wavefronts by attacking transients and providing a safe leakage path to ground for the duration of intermittent spike events occurring to power lines outside the facility. The unit is inert during normal operation but provides filtering of electromagnetic signals which often cause noise and interference to household electronic equipment.

Circuit is a hybrid design utilizing gas discharge and metal oxide varistor technology with bypass devices for RFI / noise filtering. Maximum 60,000 Amp fast switch capacity. Case is at ground potential and safe to handle anytime. Housing is standard I.C.E. heavy chassis, fully shielded, burst-proof design.

Units measure (HWD) 11/2" X 3" X 3" flat surface mounting uses service box ground connection. Includes 18" leads, 4-page owner's manual, weight 1 pound.

Fax machine and telephone line protector/filter

Facsimile (FAX) machines and Internet Computers / Modems have become a valued resource for business and personal communication needs worldwide, and the machines are more complex, expensive and delicate than ever. The machines and the transmissions they produce are subject to noise interference, static, lightning-produced voltage surges and even power line transients.

Specially designed for fax machines and computer modem use, Models 343 and 345 are combination packages featuring overvoltage control, both common and differential mode interference rejection and even spectrum filtering to improve audio response and data transfer clarity.

These multi-stage units are constructed in a fully-shielded heavy chassis and may be placed in fixed position or left on the floor behind operating table or fax machine. Telephone circuit protection and filtering are done on one side of the chassis with all modular connections. Just plug it in and you're all set. Overvoltage control uses metal-oxide varistors in balanced circuit with discrete component filtering. Noise rejection exceeds 30db. Special filtering uses low pass design with audio pass band cutoff.

AC section of unit offers 30db line isolation, overvoltage control, and even three outputs, externally mounted. Plug in up to three AC-operated items such as fax machine, computer, typewriter, etc. and spread protective functions around the office.  Unit is fuse protected at 30 amps, easily field serviceable. Extra 30AGC fuse included.

Model 343 and 345 measure (HWD) 21/2" X 4" X 4", weight 2 pounds, and come with permanently attached 6-foot 3 wire AC line cord, 4 page owner's manual.

Rotator line / remote switch transient suppressor / RF filter

Unshielded control line conductors used to operate remote switching operations, antenna rotators, and home weather stations are easily charged to thousands of volts potential referenced to ground by overhead lightning discharges, frequently causing severe darnage to equipment.

In the RF transmitting environment, these same leads often couple into transmitted energy and re-radiate signals at ground level, resulting in interference to nearby equipment tuned to other services.

Models 347, 348 and 349 solve both problems in one convenient unit. Easy to install and virtually permanent, this suppressor shunts RF currents and voltages over 20V, 50V or 120V directly to facility ground terminal connection.

Installation is a breeze and takes only a few moments. Each wire (up to 8 conductors on standard models and 12 conductors for the B models) entering from rotating unit or switch box may be attached to any of the 8/12 insulated terminals on the side of the unit. The same wire then continues from that connected point onward to control box destination. Connect the metal case to a ground rod or system and you're all set. May be used indoors or outdoors, designed for flat surface mounting, includes stainless steel grounding terminals.

Uses metal oxide varistor devices, AC or DC voltage rated, ceramic high-capacity RF bypassing components.

Packed with storage box, mounting hardware, 4-page owner's manual.
