Overview
STE Control, Protection, and Isolation Transformer
Product Details
STE
Control, protection, and isolation transformers
PRI 230 – 400 Vac, SEC 24 – 230 Vac, 63 – 2.500 VA, Elastic terminal
General data
Measurement power: 63-2.500 VA
Efficiency up to 95%
The maximum ambient temperature is 40 ° C
Insulation material grade B
Measure the output voltage of 24-230 Vac
Measure input voltage 230-400 Vac
Protection level IP 00
advantage
Good corrosion resistance and minimal noise ensured through vacuum infiltration
Reduce impulse current
Set ± 5% tap on the input end for voltage regulation
Compact mechanism achieves high power for each flow rate
Use elastic terminals for quick installation
Touch protection for wiring terminals, compliant with UVV BGV A3 requirements
Convenient fixation using sturdy metal support angle iron with long holes
DIN rail clamp is used below 250VA
standard
Control transformers comply with VDE 0570 Part 2-2, DIN EN 61558-2-2, EN 61558-2-2, IEC 61558-2-2, UL 5085-1/-2, CSA 22.2 No.66
The protection transformer complies with VDE 0570 Part 2-6, DIN EN 61558-2-6, EN 61558-2-6, IEC 61558-2-6, UL 5085-1/-2, CSA 22.2 No.66
Isolation transformers comply with VDE 0570 Part 2-4, DIN EN 61558-2-4, EN 61558-2-4, IEC 61558-2-4, UL 5085-1/-2, CSA 22.2 No.66
license
UL 5085-1/-2, CSA 22.2 No.66
application
As an isolation transformer used for safe electrical isolation of input and output terminals. This transformer is suitable for the construction of protective isolation devices and protective measures that comply with VDE 0100 requirements.
As a control transformer used for electrical isolation of input and output terminals. By design, the transformer is suitable for power supply to control devices that comply with VDE 0113 requirements.
As a protective transformer used for safe electrical isolation of input and output terminals. By limiting the output voltage, this transformer is suitable for circuit construction of SELV and PELV.
