Product Description:
The 134F7680 Refrigeration Drive is a compact and reliable motor control solution tailored for refrigeration systems. It supports flexible communication and control inputs. It includes protection features and scalable analog input handling. This drive is built to ensure safe energy efficient operation in demanding cooling environments.
This 134F7680 refrigeration drive from Danfoss supports a USB interface compliant with version 1.1 (Full Speed) and uses a Type “B” USB plug. It also features an RS485 interface with communication speeds of up to 115 kBaud. The control card can handle a maximum load of 15 mA at 10 V and 200 mA at 24 V. It includes two analog input channels that can operate in voltage or current mode. The voltage input range is 0 to +10 V and is scalable for application needs. The drive provides two programmable digital or pulse outputs. These digital outputs support voltage levels from 0 to 24 V DC and have a maximum current capacity of 40 mA either sinking or sourcing. The maximum frequency output supported is up to 32 kHz with an accuracy of 0.1 % of full scale. The system includes robust electronic thermal protection for motors against overload. The temperature monitoring of the heatsink triggers shutdown in over temperature scenarios. The unit is capable of functioning in environments up to 55 °C (with derating above 50 °C).
The 134F7680 refrigeration drive is protected against short circuits and earth faults at motor terminals U, V and W. A 24 V external power supply is supported to keep the logic alive during AC mains loss. This auxiliary power input ensures continuous drive monitoring and operation logic retention. The drive also supports mains disconnect functionality including a usable auxiliary contact.
