Please review the following points for both personal and equipment safety while operating the

linear piezoelectric amplifier.

HIGH ENERGY/VOLTAGE WA R N I N G S

Exercise caution when using amplifiers. High energy levels can be

stored at the output voltage terminals on all amplifiers in normal

operations. In addition, potentially lethal voltages exist in the power

circuit and the “output” connector. Filter capacitors store potentially

dangerous energy for some time after power is removed.

OPERATING AND SERVICES PRECAUTIONS

Operate the amplifier in an environment free of flammable gases or fumes. Do not use substitute

parts or make any unauthorized modifications to the amplifier to ensure that its safety features

are not degraded. Contact DSM for service and repair assistance.

General Precautions

♦ All insulation of leads connected to output terminals should have at least a 300V rating.

♦ Do not use clip leads in the connections. They are very dangerous for high-voltage work.

Acceptable Load Types

♦ This Amplifier is designed to drive capacitive loads only. Do not use with resistive loads.

The driver will only work properly when a capacitive load is connected to the output.

♦ Never connect an inductive or a resistive load to the unit. This would cause a short-lived

high-current pulse at the output and would damage the unit.

Short Circuit Damage

♦ Although the VF-150 OEM is protected against a short circuit on the output, it is

recommended that a short circuit condition be avoided.

♦ Never connect an "earth ground" lead (e.g., an oscilloscope ground lead) to the output

terminal. This can cause high current at the output and possible damage to the unit.

♦ If the user desires to observe the output signals using a voltage meter or an oscilloscope, the

user must ensure that the meter or oscilloscope has an input impedance of at least 1 MΩ.

Smaller input impedances could damage the unit.

RECOMMENDED OPERATION

Intended Use

DSM’s VF-150 OEM is intended to drive piezoelectric (capacitive) loads of the following types:

• Operating range –100 to +100 V

• Operating range –40 to +200 V

• Operating range –30 to +150 V

• Operating range –20 to +120 V

External power supply determines configuration. The input rail voltages should both be 5 to 10

Volts beyond the operating range. For example if -30 to +150 Volt operation is requred, typical

rail voltages would be -40 and +160 Volts. Two modes of operation are supported; the output

voltage can be set using an analog input voltage with nominal gain of 58, or the output voltage

can be set using a serial communication interface. Operation is decribed in more detail, below.
