Model ESD 201
Part Number 9110600101
INTRODUCTION
The Energy Storage Device (ESD 201) is used where a
station battery source is not available to provide circuit
breaker trip power. The ESD 201 converts ac bus voltage
to dc and stores enough energy to trip a circuit breaker one
time for up to 72 hours after ac power has been interrupted.
Warning!
To prevent personal injury or equipment damage,
only qualified technicians or operators should
install, operate, or service this device.
Caution
The ESD 201 is not a power supply and can be
damaged by continuous current draw on the
output.

THEORY OF OPERATION
ESD 201 operation is illustrated in Figure 1. Power input to
the ESD 201 is 120 or 240 Vac. This input is rectified and
used to charge the output capacitor (C1) to approximately
330 Vdc. As long as the ac input is applied, C1 continues to
be charged in this manner. However, the failure of the ac
input is what the ESD 201 is designed to protect against.
Therefore, when the ac input fails, a battery powered
oscillator circuit and an associated step-up transformer act
as the C1 charging source. (The ESD 201 can be
interconnected to the system so that the oscillator circuits
function only when the breaker being controlled is closed.
See Figure 2.) A battery charger charges the batteries as
long as the ac input is applied to the ESD 201.
CONTROLS AND INDICATORS
The pushbutton and LED indicator are used to determine if
the ESD 201 is operationally ready. When the button is
pushed, the LED lights if the capacitor has the minimum
charge of 180 Vdc required to trip the breaker. The
pushbutton and LED do not indicate whether the ac input is
being applied.
Note
The test circuit acts as a discharge path to the
output capacitor. Therefore, the pushbutton should
be depressed only long enough to observe if the
LED lights.
INSTALLATION
The ESD 201 should be connected as shown in Figure 2.
In order for the ESD 201 internal, battery-operated,
capacitor-charging circuits to operate, terminal 1 must be
connected to terminal 4. This can be accomplished by
permanently jumpering the two terminals together. Using
this approach however, the oscillator circuits will continually
be in operation if the battery is in place. This will result in
premature discharge of the battery if ac input power is not
being applied. An alternate (and preferable) approach
