Product Description:
The Bosch Rexroth Indramat VT-KRRA 2-537-20/V0 belongs to the VT-KRRA series of Electric Amplifiers. The device operates at a 24 V nominal supply and accepts battery input from 21 to 40 V.
It works with a smooth one-phase rectified voltage between 21 and 28 V. To achieve peak amplifier performance the VT 11110 must be selected when a UB ripple reaches or exceeds 10%. A red LED on the handle side shows an Undervoltage indication when battery voltage drops below 18 V. Each valve uses no more than 2.7 A under normal conditions yet rises to 3.5 A in extreme cable runs with low battery levels. Each valve needs 55 VA of power to operate efficiently. The VT-KRRA 2-537-20/V0 works with a command input voltage range from 0 to ±10V at 100 kiloohms resistance while handling input forces below ±20V. Electronic control systems supply the signal source with its ±10 V reference through b32 and z32. The system activates the output facility when operating at address a16 with voltages between 8.5 and 40 connecting 100 kΩ resistance and showing power status through a green indicator light. The position transducer uses -15 V/200 mA Class 4 power and +15 V/200 mA Class 3 power that delivers 0 to ±10 V signals through at least 10 kΩ load resistance. External electronics receive -10 V at 10 mA from c32 and +10 V at 10 mA from a32. The output system has a solenoid current limit of 3.7 amperes.
When a cable breaks in the system a yellow LED lights up at a22 to show a cable break fault message. This part consumes 24 volts at most 100 mA with normal operation status. The solenoid cable choice follows 20–20 m Ø 1.5 mm² for up to 20 meters in length and 20–60 m Ø 2.5 mm² for longer distance configurations. The shielded position transducer cable uses 4 wires with a 0.5mm² cross-section. The circuit board takes on dimensions 233.4 mm by 160 mm by 30 mm and comes with DIN 41612 plug-in connections through design D. The ideal operating and storage temperatures for the amplifier are 0 to 70 °C and -20 to 70 °C. Its lightweight 0.54 kg design fits well with control system spaces.
