Product Description:

The VT-VSPA1K-1-10I is a Proportional Amplifier used for precision control applications. Manufactured by Bosch Rexroth Indramat, this amplifier provides accurate and dependable control across different hydraulic and automation systems. The supply voltage of this amplifier is +24 VDC with tolerances of +40% and -5% to make it safe under variable power conditions.

This amplifier consumes a maximum of 50 VA of power with a peak current of 1.8 A, protected by an integrated 2.5 A time-lag fuse to protect against operational overcurrent damage. This amplifier also features a 16-position terminal strip for its electrical connection, directly located on the front plate for easy accessibility and installation on control panels. The VT-VSPA1K-1-10I amplifier comes with adjustable ramp time, which can be configured by S14 from 30 ms to approximately 1 or 5 seconds. This ramp time adjustment allows improved control of solenoid activation with gradual voltage transitions to prevent mechanical shock on connected components. This amplifier delivers a regulated output voltage of ±9 V at a precision tolerance of ±1% and a current load of up to 25 mA for stable signal control. This amplifier also includes current input signals with 100-ohm input resistance to allow its compliance with standard industrial input configuration.

The VT-VSPA1K-1-10I amplifier is compact and lightweight, and it weighs only 0.1 kg. With a width of 164 mm and a height of 104 mm, this small profile allows easy insertion into existing system layouts with minimal space requirements. This amplifier operates effectively in ambient temperatures ranging from 0 to +50 °C, and can be stored safely in temperatures from -25 to +85 °C. The solenoid resistance specifications with 19.5 ohms for operation at 800 mA and 5.4 ohms for 1600 mA operation allow this amplifier to drive proportional valves for various current requirements effectively.

Frequently Asked Questions about VT-VSPA1K-1-10I:

Q: How does the S14 ramp time adjustment improve operational efficiency in VT-VSPA1K-1-10I?

A: The adjustable ramp time reduces abrupt solenoid actuation, preventing hydraulic shock and increasing the lifespan of mechanical components.

Q: Why is the ±9 V regulated output important in VT-VSPA1K-1-10I?

A: This tight voltage regulation ensures signal consistency for proportional valve control, enhancing precision in hydraulic responses.

Q: How does the 100-ohm input resistance support signal integrity in VT-VSPA1K-1-10I?

A: It matches well with standard industrial signal sources, minimizing signal distortion and improving compatibility with control systems.

Q: Why is a 2.5 A time-lag fuse integrated into the VT-VSPA1K-1-10I?

A: This protects the unit during initial power surges or transient conditions without prematurely disconnecting during short spikes.

Q: How does solenoid resistance impact the amplifier’s valve-driving capabilities in VT-VSPA1K-1-10I?

A: Solenoid resistance settings (5.4 Ω/19.5 Ω) determine current flow, helping match the amplifier’s output to different valve types.
