FAQ
Q1 Is EI96 a fixed power or VA rating
No. EI96 identifies the lamination platform. The actual VA capability depends on the core stack height lamination material winding space conductor size allowable regulation ambient temperature insulation class and permitted temperature rise.
Q2 What information is required for quotation
Please provide the primary voltage frequency secondary voltage secondary current rated VA duty cycle voltage-regulation limit insulation requirement temperature-rise limit terminal type mounting dimensions and required safety standard.
Q3 Can Chipsen customize 380 V 400 V 415 V or 480 V primary inputs
Yes. Industrial primary voltages and multiple primary taps can be designed according to the required input system and voltage tolerance.
Q4 Can one transformer support both 115 V and 230 V input
Yes. A dual-primary series and parallel winding arrangement can be developed when required. The connection diagram and terminal identification must be confirmed in the approved drawing.
Q5 Can multiple secondary outputs be added
Yes. Independent outputs center-tapped outputs series-connected windings parallel-capable windings and auxiliary outputs can be designed according to the required voltage current isolation and regulation.
Q6 Is the transformer output AC or DC
The transformer itself normally provides an AC secondary output. If the customer requires DC output the rectifier filter regulator and load conditions must be considered separately or supplied as part of the customer's circuit.
Q7 Can EI96 operate at both 50 Hz and 60 Hz
Yes if the transformer is specifically designed and approved for both frequencies. A transformer designed only for 60 Hz must not automatically be used at 50 Hz because the lower frequency can increase magnetic flux no-load current loss temperature rise and saturation risk.
Q8 Can EI96 operate from a DC input
No. A conventional laminated EI transformer requires an alternating voltage. Direct DC input can cause core saturation excessive current overheating and transformer damage.
Q9 Can voltage regulation be customized
Yes. Regulation can be adjusted through conductor size turns ratio core stack and design margin. The buyer should specify whether the required secondary voltage applies at no load nominal load or full load.
Q10 Can Chipsen control no-load current and no-load loss
Yes. No-load current and core loss can be optimized through lamination material core assembly turns count and operating flux density. Target limits and measurement conditions should be included in the specification.
Q11 Can a thermal fuse or thermostat be installed
Yes. One-time thermal fuses thermostats resettable protectors or customer-specified protection devices can be incorporated when required.
Q12 Is an electrostatic shield available
Yes. An electrostatic shield can be placed between the primary and secondary windings to help reduce capacitive coupling and common-mode noise. The shield connection must be defined in the customer's equipment.
Q13 Can Chipsen reduce transformer hum
Core clamping varnish impregnation flux density mounting structure and lamination assembly can be optimized to reduce audible noise. The final noise level also depends on input waveform DC offset enclosure resonance and installation method.
Q14 Can the transformer be vacuum impregnated or potted
Yes. Standard varnish impregnation vacuum impregnation partial potting and full encapsulation can be evaluated according to noise moisture vibration insulation and thermal requirements.
Q15 Can Chipsen develop a replacement from an existing EI96 sample
Yes. Chipsen supports sample-based and drawing-based replacement development. Circuit information rated voltage current frequency duty cycle temperature limits and acceptance criteria should also be provided because a physical sample alone may not reveal every design requirement.
Q16 What is the MOQ
The MOQ shown for this EI96 product is one piece. Final prototype and production quantities depend on material availability construction and project requirements.
Q17 How long does quotation and sample production take
The quotation target is within three days after complete technical information is received. Sample production can be targeted within seven days after the specification materials dimensions and protection requirements are confirmed.
Q18 What tests can be performed
Available tests may include winding resistance turns ratio no-load voltage full-load voltage no-load current no-load loss regulation dielectric strength insulation resistance polarity continuity shorted turns dimensions and appearance.
Q19 Does an EI96 transformer automatically comply with an IEC or UL standard
No core model automatically guarantees end-product compliance. The transformer can be developed to support the applicable requirements but final compliance depends on the approved insulation system working voltage creepage clearance materials protection device installation and complete end-product evaluation.
Q20 Can Chipsen support long-term industrial projects
Yes. Approved materials specification control labeling traceability production testing and project-specific quality requirements can be discussed for long-term industrial programs.
