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.

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.

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.
