VT-MSPA valve amplifiers are analog amplifiers that can be used to control pump controls and proportional valves without electric feedback. The CE-certified amplifiers come with valve adjustable parameters. They are intended to be operated only for professional use and not personal use. These valve amplifiers must be kept at a distance of more than 1 meter from radio sources. The amplifiers are designed to support TH35-7.5 or TH35-15 top-hat rail assembly, and their electrical connection should be done using three tension spring plug-in connectors.

The VT-MSPA valve amplifiers are equipped with internal power supply units comprising current limiters to avoid current peaks. The amplifiers also encompass inverse polarity protection. They feature a modular design and incorporate a 3.15 A n external time-lag fuse. These high-quality Indramat valve amplifiers depict IP 20 protection class according to EN 60529 specifications and are characterized by a glass-fiber reinforced polyamide plastic housing. The amplifiers comprise a few keys and rotary switches to support their operation. We can help you with finding an obsolete digital amplifier that you may need and that is difficult to find because of a global shortage by building it for you.

• VT-HNC valve amplifiers incorporate several status LEDs on their front panels that highlight the menu levels, current operating state and error conditions.
• The Indramat valve amplifiers can be optimized using pushbuttons, and all their parameters are adjustable.
• The valve amplifiers are associated with a zero point setting, a characteristic curve generator, a short-circuit-proof output, a clocked power output stage and a ramp generator that can be adjusted up and down.
• These valve amplifiers feature a command value input that has a value ranging between 0 V and +/-10 V or 4 mA and 20 mA.
• The VT-HNC set of amplifiers does not support any form of conversion or extension and must be used only in their original state.

The valve amplifiers have a startup time of less than 1 second. The VT-HNC amplifiers comprise a 24 V nominal operating voltage with +40%/+20% tolerances, less than 2 A maximum current consumption and less than 48 W maximum power consumption. These valve amplifiers should be protected against humidity and dust.

The Indramat VT-HNC valve amplifiers must be dismounted from the DIN rail only after disconnecting the connection cables and unplugging the connectors. This should be followed by loosening the latch from its snapped-in position with the help of a screwdriver and removing the amplifier from the rail.
