Product Description:

The 137U2013 is a variable-frequency drive manufactured by Danfoss within the VLT FC 102 HVAC Drives series. It serves as an AC motor controller that adjusts fan and pump speeds in building automation systems, matching ventilation or chiller demand and reducing energy consumption. By varying output frequency and voltage, it helps maintain stable airflow or fluid circulation as operating conditions change during normal HVAC service. This type of control is commonly used where comfort, airflow stability, and pump response must track changing building loads throughout the day.

For electrical compatibility, the drive connects to a mains supply between 380-480 VAC and is designed for three-phase power, which helps maintain balanced current across industrial distribution networks. The chassis has an IP20 protection level, so live parts are finger-safe when the unit is installed inside a panel. An integrated RFI filter limits conducted emissions so the drive can share switchboards with sensitive instrumentation. The unit uses normal cabinet mounting for A, B, and C frame sizes, allowing direct installation in standard enclosures. A front-mounted Graphical Local Control Panel supports parameter entry, trend viewing, status checks, and manual start-stop control without external tools.

Several configurable options expand functionality without altering the core design. Slot B is equipped with MCB-115 Programmable I/O, which adds extra digital and analog channels for damper end switches or flow transducers. The drive uses the latest software release, and the software setup supports its safety-disable function without a brake chopper. Text and help screens are provided through a Standard Language Pack for clear local operation. Printed circuit boards are uncoated, and the remaining option positions are left empty so additional modules can be added later if the application requires them.
