Selection Requirements Selection Information
First, you should have this information before selecting
a buck-boost transformer.
Line Voltage- The voltage that you want to buck
(decrease) or boost (increase). This can be found by
measuring the supply line voltage with a voltmeter.
Load Voltage- The voltage at which your equipment is
designed to operate. This is listed on the nameplate of
the equipment.
Load Amps or Load Kva- You do not need to know both
– one or the other is sufficient for selection purposes.
This information usually can be found on the
nameplate of the equipment that you want to operate.
Frequency- The supply line frequency must be the
same as the frequency of the equipment being
operated. Micron Buck-Boost transformers operate at
60 Hertz only.
Phase- The supply line should be the same as the
equipment to be operated – either single or three
phase.
Transformer Interconnection
For three phase applications, interconnections of
transformers should be made in a junction box. Two or
three transformers may be used depending on an open
delta (2) or wye (3) connection.
5-Step Selector
The tables which follow will simplify the selection of
the buck-boost transformers. There are no calculations
needed; simply follow these 5 steps.
1. Refer to the table having the same output voltage as
the equipment that you want to operate. For example,
if you are installing a 240 volt, 6Kva single phase load,
use Selection Table Number 4.
2. Select the available line voltage across the top of the
chart which is closest to the actual supply voltage. In
the example, if the available line voltage is 213 volts,
use the 212 volt Column.
3. Read down the column until you reach an output
Kva or amps rating equal to or greater than the load
requirements. Since 6Kva, in the example, is not listed,
use the next higher rating or 7.5Kva.
4. Read across to the far left columns for the catalog
number and quantity of transformers for your
application. In the example, you will need (1) catalog
number J001K1EB1A02.
5. Connect the selected buck-boost transformer(s) in
accordance with the connection diagram specified at
the bottom of the “Available Voltage” column. In the
example, Diagram “F” would be used.
NOTE: For 1 phase connections and 3 phase open delta
connections, inputs and outputs may be reversed. Kva
capacity remains constant.
