Product Description:

The QS1L03AC Servo Amplifier is manufactured by Sanyo Denki and used in industrial automation. The amplifier implements IGBT PWM control together with a sine wave drive system to achieve operational stability. The operational frequency for the amplifier depends on either 50 or 60 Hz. Storage temperature is between –20 to +65C.

This QS1L03AC servo amplifier supports velocity, and torque along with position control functions. The amplifier requires a 2.0V command voltage with a frequency rate set at 1000 min⁻¹. Digital pulse and analog signal interfaces exist as built-in features of this amplifier. It operates at a peak output matching 150 percent of its standard current rating. The operating voltage requirement for this amplifier stands at approximately 230 V AC rated voltage. The QS1L03AC servo amplifier functions in temperature conditions between 0 to 55C. The device operates between 0 and 55C with storage humidity ranging under 90% relative humidity while avoiding condensation formation. The amplifier operates effectively within an elevation of 200m above sea level. Forward rotation motion emerges when the amplifier receives a positive command. The extent of input resistance equals 10 kΩ. Vibration resistance is rated at 0.5G. The amplifier operates effectively between 10Hz and 55Hz of frequency range. The testing period amounts to two hours in each X, Y, and Z directional plane.

A forced air-cooling system functions as an overheating prevention measure. The QS1L03AC servo amplifier classification as IP20 depends on its specific configuration type. Equipment installation becomes more efficient because of its streamlined dimensions. Its particular measurement values change depending on current system arrangements. The total weight reaches 1.2 kg based on the selected configuration type of the product. The shock resistance the amplifier can endure reaches 2G. The amplifier works with a rated current level that reaches 0.6 A.
