Product Description:

The 137H6215 is an AC variable-frequency drive produced by Danfoss and assigned to the VLT FC 302 Automation Drives series. As a speed controller for three-phase motors, it modulates output frequency and voltage to match process demand in conveyors, mixers, and other automated machinery. It adjusts motor speed to suit the load, which helps reduce unnecessary energy use during normal operation. This makes the unit suitable for applications that need controlled acceleration, stable running speed, and repeatable torque response.

The drive operates from a three-phase input window of 380 - 500 VAC, so it connects directly to common 400 V plant networks without a transformer. Its continuous output capability is 15 kW, which is equivalent to 20 HP and provides adequate headroom for mid-sized pumps and fans. Because it uses three-phase power, the drive monitors phase balance during operation. The enclosure grade of IP54/Type12 N3R helps keep dust and water splashes away from the bus capacitors and IGBTs, while European metric cable entries simplify cable gland selection. Within the VLT FC 302 product group, the identifier 302 marks this drive version, and the language pack is set to Standard so keypad messages appear in the default set. The drive is supplied without a brake chopper, so rapid deceleration requires an external resistor.

The A slot is marked No Option, Adaptation B shows No adaptation, and the D slot is labeled No D Option. Only the B slot is populated with the MCB-103 Resolver Option for position feedback. There are no C0 or C1 cards, and the C-software slot is blank, yet a Graphical Local Control Panel is installed for parameter access. EMC compliance is supported by the integrated RFI Filter, while a coated PCB resists moisture and airborne oil. No separate mains option is installed, so the standard input terminals handle the incoming power connection directly.
