◆Product introduction

BK/JBK Single Isolation TransformerSeries is used of electromagnetic induction principle and developed accordingto the latest CNC servo system parameter.

These products are absorbed merits ofsame kinds of products at domestic and aboard, with constant improvement andfurther by Saio Electric over years experiences. Used advanced technology andpreciseness design to proceed on manufacturing, and select foreign advancedterminals, with excellent performance work reliablelow energy consumptionsmall volumeWiring Safetyextensive applicability, extracharacteristics, it is an ideal voltage power supply.

Apply to 5060HzRated supply voltage ≤1000V at AC Circult , Serve as Control Powersupply for Machine Tool and mechanical Equipment, as power

supply of operating illumination andsignal lamp ; Also be a mini-type motive power.

◆The function of single phase isolation transformer

The main function of single phaseisolation transformer : make primary side and secondary side electric insulationcompletely, also isolates the loop.

In addition, use high frequencydissipation of iron core, suppress high frequency clutter afferent controlloop. Use the insulated transformer to levitate the  ground twice, only can be used for less powersupply short circuit occasion. Meanwhile, thesecondary side of system no voltage to ground ! play a role of

isolation dangerous voltage.

Ambient air temperature is not over 40℃no lower than -25℃
3
Relative air humidity: The average maximum relativehumidity of the wettest month is 90%

4No strenuous vibrationand impulsive place;

5The place is themedium of no explosion hazard, no enough corroding metal and destroy insulationgas and electric conduction dust.

6The place is noinvasive by rain and snow.
7
Waveform of supply voltage is similar to sine wave.

◆ Structural feature

This product comply to JB/T9646 and relativestandards, iron core of BK model is Shell type , which made of by silicon steelsheet with dashing, cutting,    convoluting.

Iron Core of BKC Model is heart type,which made of by silicon steel sheet with rolling C shape.coils of BKJBKseries are multiple cylindrical winding,The  primary, secondary coils are wound separately.Usually except primary windings, There are two general secondary windings. Oneis "light winding" supply voltage for local lighting ; Another is"control winding" supply the machine to control the voltage neededfor the electrical apparatus. The same transformer is "controlled"and "illuminated" by two windings, the secondary winding is separatedwinding of independent winding. The terminal of light winding is grounded, Someofthem also use the way to draw the joint , to extract 6.3V Voltage supply signallamp from secondary control winding .

◆  Attention
1. Before purchasing, estimate the total capacity of theappliances you use, and select a transformer with considerable capacity toensure that the transformer is not burned at instantaneous starting.

2. When you use a multiple winding(multiple control voltage) transformer, clarify the capacity allocation of thewinding and remain the residual amount so as not to burn the transformer.

3. Before installation, you shouldcarefully check whether the data listed in the nameplate is in line with yourrequirements. After the confirmation is correct,  the use can be installed.

4. Electricity work, transformer coreand coil will be fever, but the temperature rise of less than 80 ℃) belongs tothe normal phenomenon, if the temperatureover 80 ℃, even smoking, should cutoff the power switch, to recheck electric capacity you are using.
5. During transportation, avoid collision as much as possible. Do not sufferfrom moisture. When used, please pay attention to maintenance to protecttransformer service life.
