Alhdara Electronic(shenzhen) Ltd.

We are offering Toroidal Transformer. 1) Little flux leakage，the ring is very close，uniform magnetic circuit and completely closed，no air gap in the magnetic circuit， therefore，particularly small external magnetic flux leakage. (2) Small losing，low-temperature，high efficiency The magnetic induction B value transformer strength is in the design of about 1.7 T (saturation magnetic induction intensity up to 1.9 T ), less winding turns， small internal resistance，thereby reducing the loss of copper and iron and improve the efficiency of the transformer，winding Coil around the ring core， so good heat dissipation, low temperature rise. (3) Strong ability of overload Winding due to the resistance of small, quick reaction, when the additional load current suddenly increased, the toroidal transformers can quickly upgrade the current to ensure the load needs. Especially in the HiFi stereo equipment，it is very suitable to use this kind of toroidal transformer. (4) Small size, light weight. Winding transformer, not on the core framework, as long as packed insulation, or with epoxy resin powder electrostatic spraying, you can direct routing, because the magnetic induction intensity B value can be made higher, the size of small core，Use less the copper，compare with the EI transformer can be reduced about 30-40 percent. (5) Low noise, no vibration Because the iron sheet is very tight，no middle joints，electromagnetic are much improved after the iron sheet heat treatment，the copper wire roll on the insulating iron sheet ，no clearance in interior，so when working the noise is low and no vibration . (6) Good Technics Free combination according the iron sheet size, no need mould fee, so it is high universality of design the roll iron sheet is more simple than the EI，C，R，so the cost is low .

We are offering Voltmeter. * Standard Size and Specification * The Core is 10 A / D converter microcontroller, high accuracy, wide measuring range (30V ~ 400V) * get Power directly from the testing , and only need 2 wires can work normally and it is able to access accurate testing, no need match with low-voltage power adapter * Conditions of Use: －20℃～85℃、and relative humidity ≤ 80% (25℃)

We are offering Single Electronic Fixture. 1.Beautiful design suitable for Mosque and home use. 2.Azan Makkah & Madina & Al-aqsa. 3.Day light saving format to adjust pray times. 4.Remote control and keypad for easy setting. 5.795 cities can be downloaded. 6.Azkaar for each quarter hour can be effected with 12 kinds of sounds which can be choosed. 7.Sound can be adjusted at 7 levels. 8.Gregorian and Hijri full date. 9.Full time show with 12/24 H format. 10.Help sound for setting. 11.Reminding before 15 mins for next pray time. 12.Hijri month LED indication. 13.Prayers Timing automatic daily updated. 14.Backup battery save date, time and setting. 15.Can show temperature. 16.Can save latitude and longitude for 5000 cities.

We are offering Electronic Ballast. * No noise, no starter, can start up at low voltage. * More than 20% energy saving, comparing with the same power of inductance ballasts, energy saving effect is obvious. * Low losing, The Power Factor more than 0.6, fire safety protection. * Standard power input to terminal and the ground terminal, easy to assemble. * Green aluminum lighthouse, fire-proof PC shell.

We are offering Regulator. *Digital system with 16 stages (where it can jump to the required stage without passing the other stages) . *Working as a voltage fixer ± 4% volt and equipped with a compensation circuit to continue connection between stages. *Protection from high voltage which resulted from the network or the regulator at 245 voltages. *Protection from shortage and from current increase by a magnetic thermal breaker. *Transformer for transferring to the network voltages, and to cancel regulation when necessary. *Delay working at the operating beginning for ten seconds in order to stabilize with network, it possible to control the time for 3 minutes. *Delay in organizing operation to avoid network fluctuations, this delay will be canceled at 200 voltages. *Simultaneous: Since exchange of regulating pads is synchronously with zero voltage wave in order to avoid sparks on contacts.
