H.3 Alternative Power Sources
As an alternative to the 120 VAC input, an external DC power source can be
used. The DC power source should have a current capacity of at least 500 ma
DC and a voltage from 8 to 14 VDC. Actual current consumption will be
approximately 250 ma standby and 375 ma while phoning and speaking, plus
whatever current is required to charge the internal 6 volt, 4 AH gel-cell battery.
This supplemental charging current will be roughly 25 ma when the battery is
already fully charged, and up to 200 ma if the battery is being recharged after a
discharge. Option cards such as analog, remote supervisory control etc. will
also moderately increase the current being drawn.
DC power should be connected via a standard single-circuit “MINI” plug,
inserted into jack AJ1 located in the upper right hand corner of the main circuit
board. This jack must be configured to accept DC power input by placing a
jumper shunt across the lower pair of pins on the three-pin header JB8, located
next to AJ1. The positive (plus) side of the power source must go to the end
“tip” of the plug; reversing this polarity can damage the product.
Note:
Note that AJ1 is a dual purpose jack which may be used either for audio
output or DC power input, but not for both simultaneously. Note also that the
AC power fuse FU1 is bypassed with this configuration. It should be
removed to avoid confusion.
The front panel ON/OFF control will operate as with standard 120 VAC power
input. If the external power source is interrupted, the unit will switch to gel cell
battery power and go into power failure alarm.
The Verbatim autodialer is capable of being powered by other types of power
source, including 240 VAC, on special order. Contact factory for details.
