2) Operation
a) It is recommended to complete the connection with the piezoelectric actuators before
switching on the [POWER] switch.
b) Make sure the bias voltage knob is set to zero if bias voltage is not needed.
c) After switching on the
〔
POWER
〕
switch on the front panel, the device will be ready
in function in a few seconds. The output voltage can be control with bias voltage
knob or the input signal.
3) Over load protection circuit
The built-in protector will be activated when the peak current is more than 5Amp or
the average output current is more than 1 Amp. When the built-in protector is
activated, the
〔
OVER L.
〕
LED on the panel will turn on. Press the
〔
RESET
〕
switch
to reset. Only reset the
〔
RESET
〕
switch after make sure there is no short circuit,
overload and etc.
4) Power bandwidth
For reference the power bandwidth of the MTAD3001, some examples of the driving
conditions are summarized as follows.

The built-in protector activated as the average output current goes above the
threshold.)
5) External control of built-in protector
The built-in protector is designed to be access easily from customer control system.
The circuit protector can be controlled remotely from an external circuit by TTL
High signal level of control signals.The circuit is shown as follows.
