Caution As this is a small closed volume unit the only cooling of the internal electronics is by
radiation from the case. Accordingly the following rules must be adhered to to ensure that the unit will
operate correctly.
100% Duty Cycle Loop Drive Voltage 8 Volts
80% duty cycle Loop Drive Voltage 10 Volts and
50% duty cycle Loop Drive voltage 12 Volts
