SMR AEC

The Allis Electric ES0948-48V18.8A is a switching mode rectifier (SMR) module designed to provide up to 18.8A of output current into a 48V nominal system. This rectifier has been designed especially to be used in conjunction with a battery to provide an uninterruptible DC power system. The low noise and high reliability make it ideally suited to telecommunications applications. The rectifiers are designed to slide and plug into a single magazine-SR1948-9, designed for a 19” rack, which can accommodate up to 9 rectifiers and up to 32 rectifiers can be configured as a system using one control and supervisory unit (MCSU2048).

The ES0948 Switching Mode Rectifiers are highly compact, high efficiency, fully featured switch mode rectifiers which can operate in a modular rack environment with overall control from the control and supervisory unit MCSU2048. With overall control, such features as active current sharing, accurate battery voltage regulation, battery recharging current limit control, automatic battery equalization and battery temperature compensation are achieved.

The ES0948 rectifier modules incorporate a microcontroller-based control card which incorporates the control and supervisory facilities of the SMR. The microcontroller enables digital communications to the MCSU2048 as well as to the outside world (via the MCSU2048), so that is possible to examine the operating parameters and, if necessary change them to suit a particular situation, from a remote location, even a distant one if a modem is used. This method of monitoring and control opens up entirely new methods of routine and emergency maintenance procedures.

The ES0948 module has been designed for small to medium sized Rack Power System, this highly compact rectifier module combines high reliability with state-of-art performance and features, including:

1. Innovative single phase input stage with wide input range (90-275Vac)

2. Power factor >0.99. Sinusoidal input current. Meet EN61000-3-2.

3. High efficiency (over 92%)

4. Microprocessor based.

5. Active or passive load sharing.

6. Rear “push in to plug in” connection for AC, DC and communications link.

7. Mass less than 1.9kg

8. Exceptional power density

Apa itu AVR dan mengapa/kapan kita membutuhkanya?

 

AVR singkatan dari Automatic Voltage Regulator, yang lebih dikenal dengan sebutan Stabilizer yang berfungsi untuk mengatur tegangan listrik secara otomatis. Kita membutuhkan AVR/Stabilizer jika menemukan gejala-gejala sebagai berikut (diasumsikan alat tersebut baru terpasang atau tidak bermasalah);

1. Bola Lampu yang redup atau berkedip

2. AC (Air Conditioner) yang tidak dingin

3. Pendeknya umur alat-alat listrik yang dipakai (rusak sebelum waktu yang ditentukan oleh pabrikan).

4. Hasil Produksi yang tidak sempurna dari mesin di pabrik anda

Hal-hal tersebut disebabkan oleh perubahan tegangan pada sumber listrik di daerah anda yang tidak menentu yang pada umumnya disebabkan oleh beban yang berlebihan di area anda.
