Figure 61 shows the internal connections for use on a 115-volt A.C.
line and Figure 62 the internal connections for use on a 230-volt
line. This Tungar is made for a 60-cycle circuit, 25-30, 40-50, and
125-133 cycle circuits.

F. The Twenty Battery Tungar

Catalogue No. 221514

This Tungar will charge ten 6-volt batteries at 12 amperes, or twenty
6-volt batteries at six amperes. Figure 63 shows the complete
rectifier, and Figure 64 shows the rectifier with the side door open
to show the internal parts. This rectifier will do the work of two of
the ten battery Tungars. It is designed for operation on 60 cycles,
230-volts. On special order it may be obtained for operation on 115
volts and also for other frequencies.

The twenty battery Tungar uses two bulbs, each of which is the same as
that used in the ten battery Tungar, and has two charging circuits,
having an ammeter and regulating switch for each circuit. One snap
switch connects both circuits to the supply circuit. The two charging
circuits are regulated independently. For example, one circuit may be
regulated to three amperes while the other circuit is delivering six
amperes. It is also possible, by a system of connections to charge the
equivalent of three circuits. For instance, five batteries could be
charged at six amperes, five batteries at four amperes, and five
batteries at ten amperes. Other corresponding combinations are
possible also.

General Instructions and Information on Tungars

Life of Tungar Bulbs. The life of the Tungar Bulb is rated at 600 to
800 hours, but actually a bulb will give service for 1,200 to 3,000
hours if the user is careful not to overload the bulb by operating it
at more than the rated current.

Instructions. Complete instructions are furnished with each Tungar
outfit, the following being those for the ten battery Tungar.

Installation

A Tungar should be installed in a clean, dry pl
