Full-spectrum harmonic filtering (3-51)

OTSOPRO filters out low-frequency harmonics (3 to 13). OTSOMAX goes further: it filters out all harmonics in the frequency range 3 to 51 , balances the load and improves the power factor even in heavy grid conditions. The result is, among other things, less heating and interference in cables – as well as measurable savings in critical areas such as the process industry, data centers and hospitals.

Main features

Efficient filtering of harmonics

Filters low-frequency harmonics (3-51) in the power grid.

Reducing interference with high loads

This reduces interference caused by motor drives and other high loads.

Protection against unnecessary loads and downtime

Protects your power grid and equipment from unnecessary loads and costly downtime.

Longer service life and improved reliability

Extends the life of devices (e.g. transformers) and improves the reliability of the entire network.

What is OTSOMAX suitable for?

Process industry and heavy loads

Inverters and inverters generate broadband harmonics. OTSOMAX filters 3 to 51 harmonics and reduces device heating and motor drive failures.

Hospitals and laboratory environments

Sensitive measurement and imaging equipment needs clean electricity. OTSOMAX cuts out interference from the source (inverters, frequency converters) and helps prevent error displays and unnecessary downtime.

Data Centers & Critical IT

UPS systems and switching power supplies put a strain on the grid. OTSOMAX reduces harmonics, reduces losses and improves the power factor, which supports energy efficiency and reliability.

New and renovation sites with a lot of power electronics

Solar inverters, storage, and modern machinery bring higher harmonics. OTSOMAX ensures that the network remains within the limits of standards even with future loads.

OTSOMAX filters the entire spectrum (3 to 51 harmonics), reduces heat and energy losses, improves the power factor and protects the equipment from interference. The result is a smoother grid, longer device life, and measurable savings – especially in environments with a large number of inverters and drives.

Calculate your savings

Enter the annual consumption, the price of electricity (cents/kWh) and any fees and costs. The calculator shows the estimated annual savings and payback period immediately – change assumptions (e.g. savings percentage) and see the effect immediately.

OTSOMAX Functions and Device Specifications

Reactive power

OTSOMAX corrects the power factor to the desired size (factory setting 0.99), eliminating both inductive and capacitive reactive power (reactive power intake and delivery) as needed. Any reactive power fees will be reset.

Reactive power correction 50-800 kVar

electrical load

The device has an additional function that effectively corrects unbalanced load from the network side

Harmonics caused by oblique loads are reduced

The current to the neutral conductor caused by the electrical load is almost completely eliminated

Remote monitoring

OTSOMAX measures and records the most important electrical parameters, which can be visually viewed in the OTSOMAX monitoring portal immediately after the device is commissioned.

Installation / maintenance

OTSOMAX is installed in parallel to the main switchboard and does not require a power outage. The device is almost maintenance-free. The filter of the equipment must be cleaned 1-2 times a year (every 6 months in a dusty center). The procedure can be carried out by an authorised electrical professional.

Size options

50 kVar 600x400x1115

100 kVar 415x875x1960 (CAB model)

Modular Equipment Cabinet (RACK Model) 100-800 kVar 820x820x2150

Harmonic correction

OTSOMAX filters low-frequency harmonics from 3 to 51 harmonics (e.g. motor drives).
