The E-461.00 piezo driver is alow-cost amplifier for high-volt- age PZTs. It can output a peak current of 0.5 mA and an aver-age current of 0.3 mA. Becausethe unit requires an operating current of only 80 mA @ 12 V, battery operation is possible. The E-461.OE is the OEM ver-sion of the E-461.00 amplifier.The OEM module does not pro-vide manual controls. All input connections are via 6 header pins located on the bottom. The HV output is via a coaxial cable with LEMO connector (ERA.0A.250.CTL). The moduleis designed for mounting oncircuit boards. The electronics are fully enclosed in a metal case. The E-461.00 and E-461.OE can be operated in 2 ways: Output voltage can be set by aDC-offset potentiometer (not supplied with E-461.OE) in therange of -10 to -1000 V. II. External Control:

Technical Data

Output voltage is controlled byan analog signal in the range of 0 to 10 V, applied to the BNCinput. Multiplying by the gainfactor of -100, an output volt-age range of -10 to -1000 V results. The DC-offset poten- tiometer adds a DC bias to the input, allowing continuous shifting of the input range between 0 V to +10 V and -10 Vto 0 V (see page 6-52).The E-461.00 and E-461.OE arenot equipped with active dis- charge circuitry but a 5 Mh/ 3.9 nF RC network. Therefore,PZT discharge times will differfrom charge times. If dynamic (>1 Hz) PZT operation is required, please consider the E-463 or E-507 amplifiers (see page 6-40and see page 6-23).
