Welcome
DEM Manufacturing is the European distributor for MTE's range of power quality products.
MTE is a world leading manufacturer of power quality products designed to improve the reliability of power electronic systems and adjustable frequency drives. MTE design and manufacture Harmonic Filters, line/load reactors, DC link chokes, dV/dT and sine wave motor protection filters. These products are typically used in industrial plants and commercial buildings where non-linear loads and attendant harmonics produced by these loads are present.
DEM Manufacturing offers harmonics distortion testing for manufacturers and processors required to meet G5/4 for power quality. The on-site test provides a measurement of the harmonic distortion level on systems ~ 2000A.

Harmonic Filters
MTE harmonic filters solve the problem of harmonic distortion on virtually any two or six pulse rectifier. These power supplies are commonly found in electronic equipment such as adjustable speed motor drives, servo drives and other equipment. ...more
Line / Load Reactors
MTE reactors help keep your equipment running longer by absorbing many of the power line disturbances which otherwise damage or shut down your inverters, variable speed controllers, or other sensitive equipment. ...more
DC Link Chokes
DC link chokes offer the advantage of maximizing the circuit inductance for power quality reasons, but without causing an AC input line voltage drop. DC link chokes can be used individually or in pairs with one each on both the positive and negative bus. ...more
dV/dT Filters
dV/dT filters are designed to protect AC motors from destructive effects of long-lead peak voltages. Depending on the turn-on time of the power semiconductors used in the inverter, size of the motor and cable length, these peak voltages can be extreme. ...more
Sine Wave Filters
MTE Sine-Wave Filters provide a 5% THVD sine-wave output voltage for motor and cable protection when driven from PWM inverters with 2-8 K Hertz switching frequencies. ...more
