Product Description

The VT-VSPA2-50-10/T5 is a valve amplifier designed by highly trained engineers of the reputable Bosch Rexroth Indramat company. This valve amplifier is designed according to international quality and safety standards, it is suitable for controller proportional pressure control valves, and pilot operated directional valves (type .WRZ, from series 7X) without electrical position feedback. The valve amplifier features four command values tat can be adjusted by means of potentiometers, it also features command value call-ups with LED indicator lamp. The differential input of this servo amplifier can be switched over to current input. The valve amplifier also features an enable input with LED indicator lamp. A reverse polarity protection is also provided for voltage supply. The amplifier is intended to be used as an integral components of industrial machines and should be protected from external interference at all times. The operating voltage required by this valve amplifier is about 24Volts, however the valve amplifier can also function with an input voltage as small as 18 volts, or as high as 35 volts. The current consumed by this amplifier during operation is less than 1.2 amperes, also the amplifier consumes power that is less than 30 volts per ampere. An exchangeable fuse is integrated into the valve amplifier, the fuse has a rating of 2.5 amperes. At an operating temperature of 20 degree Celsius, this valve amplifier maintains a response voltage of 16.8 volts, and a release voltage of 2.4Volts. The coil resistance of the amplifier is 2120 ohms, while the ramp time falls between 30 milliseconds to 1 seconds. The permissible ambient temperature for this valve amplifier falls between 0 to about 50 degree Celsius, the amplifier also has a total weight of 0.13kg.
