The difference V3F16L and V3F25

V3F16L KONE elevators and V3F25 belong to two different drive systems, two drivers have a difference in the nature, then where do they differ? From the structural use, maintenance and other aspects of commissioning a brief description of the differences between V3F16L and V3F25
V3F16L difference with respect to structure and use V3F25: V3F16L integral part of the drive cabinet, which has three internal circuit board, IGBT is a seven-piece unit, and the internal circuit includes a rectifier. Used for low-speed series KONE elevator or freight elevators.

When using V3F16L drive system the way it’s speed device is a tachometer generator to complete.
V3F25 drive belonging to split the drive cabinet, which has only two boards, called A1 and A2 board panels, it uses three high-power tube discrete IGBT. It for a small room used for sightseeing lift or elevator, used for fast running speed elevators.

In addition to its input port of a rotary encoder, a weighing device, and a motor speed generator such as a thermistor devices are cured (HCB) 385: A1 board.
V3F16L with V3F25 difference in terms of commissioning maintenance: When V3F16L maintenance is relatively easy to maintain, more convenient disassembly. When V3F25 complex disassembly, A1 board more susceptible to failure, the failure is not very easy to repair.

Ordering V3F16L and V3F25 drives

About the V3F16L and V3F25 drives

Elevator and escalator control systems are built around a relatively small number of serviceable assemblies: the drive and motion controller, the main control or mother board, the power stage, the encoder feedback interface, and the door or brake control module. The elevator is one of those assemblies, and like every board in the cabinet it is replaced on a different service interval. Each carries its own set of reference numbers depending on the original equipment manufacturer and the revision of the installation.

Every elevator we supply is inspected before dispatch. Boards are checked for physical damage, capacitor condition and connector integrity, and are packed to survive international transit. Where a superseded revision is the only one available, we state that clearly and explain the substitution so that the installing engineer can make an informed decision.

V3F16L vs V3F25: buying guidance and compatibility

Before ordering elevator, confirm three things. First, the exact part number and revision from the failed unit. Second, the equipment model and controller family it was installed in, since the same board can be used across several product lines. Third, whether the installation is a traction lift or an escalator, as the duty cycle and current rating differ between the two.

If you are unsure which revision of the elevator you need, send a photograph of the nameplate and the existing board alongside the fault description. That is usually enough for our team to identify the correct replacement without a site visit, and it avoids the cost and delay of returning an incompatible part. We are also happy to advise on the other serviceable assemblies in the same controller, so that a planned shutdown can cover several wear items at once.
