5.23 AC Series (Amp Clamp)

Alpha Technologies’ Amp Clamps are designed to protect active and passive equip-

ment (such as amplifiers and power inserters) from voltage surges and transients. Amp

Clamps can be ordered as retrofit kits, or factory installed in the desired host hardware. A

Product/Serial Number label is included with each kit so that retrofitted equipment can be

easily identified. The Amp Clamp circuit consists of two, rugged SCRs (silicon controlled

rectifiers) connected in an inverse parallel configuration with a steady state current rating of

35 Amps and a one cycle (8 ms) pulse rating of 500 Amps. The SCRs are triggered into

conduction whenever the Amp Clamp’s bi-directional trigger diode senses the presence of

voltage transients exceeding its 104 - 115 Volt peak threshold. The fast response trigger

diode gates the appropriate SCR ON (in nanoseconds) to shunt the surge current to

ground, effectively protecting sensitive equipment from transient overvoltage conditions.

The Amp Clamp is compatible with the following host hardware: C-COR PS-550-C power

inserter, PS-900-C power inserter and T500 amplifiers (6 & 8 port); G.I./Jerrold SSP-PI

power inserter, SSP-3 two-way splitter and SSP-(7, 9, 12, or 16 ) directional couplers;

Lindsay LPI-100 and 1GHz LPI-100 power inserters; Magnavox 4-LPI, 5-LPI, 8-LPI, 49-

LPI and 59-LPI power inserters; RCA PI-1 power inserter; RMS CA-5400 and UP-6400

power inserters, and CA-5402/RFI two--way splitter; Scientific Atlanta SAIF-RFI power

inserter; Regal RPI-60 (blue) power inserter; and Antronix RPI-60 (green) power inserter.

If your equipment is not listed, contact Alpha Technologies for availability.

5.24 CAT-PAK (Computer Aided Training)

Computer Aided Training for power supply maintenance is available for either MAC® or

IBM® (and compatible) formats. Technicians can learn and develop maintenance skills at

their own pace before leaving the office, thus reducing overall maintenance time and

standardizing maintenance practices. Even though the CAT-PAK training program was

developed for use with AP Series power products, the overall information can be applied to

XP installations. The program can be manipulated entirely by the user without the need for

assistance. Complete system packages, including hardware and software, are available

from Alpha Technologies. Please specify format and disk requirements (3 1/2" or 5 1/4")

when ordering.

5.25 Instructional Videotapes

Instructional videotapes are available for Alpha power products including Product

Overview, Theory of Operation, Installation, and Maintenance. Developed primarily for use

with AP Series power products, the tapes contain useful information that can be applied to

XP installations. Each tape is available in either NTSC (VHS) or PAL formats and covers

all aspects of the Alpha Standby Power Supply. Transcripts of each tape are available

upon request.

"Alpha Technologies: Market Leader in Standby Power" (P/N 048-082-00) is a 20

minute presentation which highlights standby power products and emphasizes reliability,

ease of operation and customer service.

"The Alpha Standby Power Supply" (P/N 048-070-00) is a 10 minute conceptual over-

view of the Alpha standby power supply. The tape covers the advantages and disadvan-

tages of forward and reverse transfer systems and compares them to Alpha's approach to

standby power.

"Installing the Alpha CATV Standby Power Supply" (P/N 026-006-B4) is a 20 minute,

step-by-step, description of the installation process. The tape includes ground and pole-

mount applications, start-up procedures and testing the unit.

"Power Supply Maintenance for AP and AM Series Power Products" (P/N 026-006-B2

[108-3]) is a 30 minute presentation that covers all aspects of AP Series standby power

supply operation and recommended maintenance procedures.
