Control Transformers
Control Transformer ENT.PST Series
Summary
ENTES control transformer ensures the safe operation of measuring equipment through 24 VAC voltage used in electrical control cabinet. The input voltage of the control transformer is fixed (230 or 400V) or the interval is optional (400;: 230 + 15-15). The electrical connection is realized by terminal block, and the cross section is fully selected to meet the maximum current. The control transformer is designed to operate continuously at 50'C ambient temperature F at rated power. Therefore, manufacturers of electrical cabinets need not consider adding expensive additional safety factors to rated power. All ENTES control transformers are marked with CE and conform to EN standard. |

ENTPST Series of Control Rake
Summary
The ENTES isolation rake is isolated from the secondary voltage to ensure the safety of the secondary terminal.
The input and output voltage of isolation rake is fixed (230 or 400V). The electrical connection is realized by terminal block. The cross section is fully selected to maximize the current. All ENTES height-isolating rakes have CE mark, which conforms to EN standard. |
Isolation transformer
●For locations requiring current isolation.
●Surge current attenuation
●Used to create neutral points in networks without neutral points.
●Other VAs and/or voltages are provided as required.
●Efficient
●The maximum VA value of 2500VA can be provided as required. |
Technical Characteristics of Isolation Transformer
●Compliance with EN 61558-2-2
●Class 1 transformer (with grounding terminals)
●Vacuum ULV0 impregnated varnish to ensure silent, efficient and moisture-free work
●Reduce the main grounding impedance to the lowest level by air gap welding of metal sheet
●Working at ambient temperatures rated up to 50C
●High permeability of core
●High quality copper windings:
●Minimum primary/secondary isolation voltage: 4400 VAC for 400V and 3600 VAC for 230V |
