PSR4/5A-212

Product Description:

The PSR4/5A-212 Servo Power Supply from Kollmorgen provides stable and controlled power to servo drives in industrial automation. This small 10x10x5 cm and 500g unit is a universal solution for many applications. One of the key features is the wide input voltage range, 220V and 110V systems are supported. The main AC line input voltage is 160-253 VAC, and the control AC line input is 90-132 VAC, this makes it easy to integrate into different electrical setups. The PSR4/5A-212 connects via USB-C, making setup and configuration easy. Digital communication makes data transfer and control efficient. A key aspect of the PSR4/5A-212 is the power output. The internal heat dissipation is 120W; this is the basis for the thermal management design to keep the unit at operating temperature and long-term reliability.

The unit delivers 325 VDC main DC bus output; this is the power source for the connected servo drives. This high-voltage DC output is for efficient power delivery and precise motor control for demanding industrial applications. The power supply has a peak power dissipation of 5.6 kW. This is for high power surges during dynamic operation to ensure reliable operation under heavy load. The continuous power dissipation is 40W; this is for sustained power load. The PSR4/5A-212 has regeneration capability, which is important for servo applications. It has an internal regeneration shunt resistor of 25 Ω, which dissipates the energy during braking to prevent overvoltage and smooth deceleration. The unit also supports external regeneration for even more braking capacity.

The minimum external regeneration shunt resistor is 8.8 Ω, and the peak shunt regulator current is 44.3 A in this configuration. This is important for applications with frequent acceleration and deceleration to improve efficiency and reduce mechanical wear. The internal regeneration shunt resistor supports a 15A shunt regulator current. The PSR4/5A-212 is designed with thermal management in mind. Besides the high internal heat dissipation, the design itself is very efficient, which contributes to the overall thermal stability. This is important for reliable operation in industrial environments where temperature fluctuations can affect performance. The power consumption of the unit is 10W, this is the power for the internal operation and control circuitry. This low power consumption contributes to the overall energy efficiency of the system.
