ENV 300 is the mid-power amplifier module of the modular multi-channel amplifier system ENV by piezosystem jena, delivering 300 mA permanent output current and −20 to +130 V output voltage for semi-dynamic applications (e.g. PX 100 stage up to about 500 Hz). The module features an LCD display, manual potentiometer, 0–10 V analog modulation input and a 1/16 monitor output (BNC).
Closed-loop versions integrate SG (strain gauge) or CAP (capacitive) servo modules; the CLE version adds Automatic Sensor Identification (ASI). A soft-start function protects the piezo ceramics on power-up.
System configuration: combine one ENV 300 with an ENT 150 power supply module, or two with an ENT 400. Actively cooled casings are recommended when using more than one ENV 300. Desktop (28–84 TE) and 19-inch rack casings are available, freely combinable with ENV 40/150/300/800 modules.
