REOVAR RRT/RRTW

Single-phase toriodal variable transformers (auto windings, open, IP 00)

REOVAR RRT/RRTW

Unique Selling Point


  • Closely stepped adjusting of output voltages
  • Frequencies of 50 - 400 Hz
  • No EMC-Problems
  • Low heat dissipation
  • Comparatively large loads with small dimensions
  • Wide range of accessories

Description


REOVAR toroidal transformers from the market leader for variable transformers regulate the output voltage in fine steps at constant current at the output. Our toroidal transformers are suitable for frequencies of 50 - 400 Hz - other frequencies on request.

The particular advantage of this series is to maintain the sinusoidal shape - like that, EMC problems cannot occur. The special winding core of REO produces no stray fields and low voltage case .

Type RRT/RRTW with an adjustable spindle to allow table or wall mounting. Sizes M4 - M61 have an optional center fixing nut.

  • Input voltage: 230 V 50/60 Hz
  • Output voltage 0-230 V oder 0-260 V
  • Ambient temperature max. 40° C
  • Connection group IO

 

REO toroidal variable transformers conform to EN 61558-2-14

Technical Data


  • Input voltage : 230 V
  • Output voltage : 0 - 230 V
  • Output Current : 1 - 32 A

Increase factor

  

Factor ki expressed as a relationship to no load voltage (U02) over primary voltage (U1)
Curve a) Type M4, M7 - M12
Curve b) Type M5, M61, EN7 - EN10

 

 

 

Factor kk relative to operation time t.

 

Maintenance:

The brush-roller has a sintered-bronze bearing, which is lubricated for two years of operation.

Seized or worn carbon rolls must be replaced immediately. From time to time the contact surfaces of the windings should be cleaned with a stiff brush to remove adhered dirt (dust and carbon abrasion).

Maintenance manual on request. 

 

Accessories:

  • Collet knob FZ 60 for M4  to M 61
  • Collet knob FZ 90 for M7 to EN10
  • Scale 90 for collet knob FZ 60
  • Scale 120 for collet knob FZ 90
