Power Supply

Bentuk gelombang menunjukkan kualitas suatu sistem supply daya, sebagaimana juga pada Power Supply merupakan suatu modul daya perangkat yang berguna operasinya  sebagai backup power atau daya sebagai cadangan listrik bila sumber energi listrik regular utama dari PLN kondisinya off atau mati dimana sudah biasa kondisi tersebut di instansi daerah atau pedesaan. Sangat penting mengetahui bentuk gelombang yang dihasilkan oleh UPS sebelum memilihnya, karena akan mempengaruhi kinerja dari beban yang dihubungkan dengan UPS. UPS memiliki karakteristik yang berbeda tiap tipenya, ini dikarenakan UPS tiap tipenya memiliki fungsi kerja kebutuhan yang disesuaikan pada perangkat elektronik yang di_supply dayanya. Tipe ups seperti line-interactive, online, offline memiliki karakteristik kerja yang berbeda-beda seperti pada mitra pengabdian kita yaitu pada rumah sakit mardi waluyo Blitar ini kebutuhan UPS diperuntukkan pada alat medis dimana alat medis ini membutuhkan presisi dan akurasi yang tinggi untuk pengukuran obyeknya. Agar mendalami merosotnya penyebab kepresisian dan akurasi pada alat medis maka kita melakukan pengabdian dengan pembuktian gelombang perangkat UPS tiap tipenya agar teknisi rumah sakit dalam memilih tipe UPS tidak salah penempatannya untuk obyek yang bagaimana dan seperti apa operasinya. Artikel tentang Pengabdian ini dilakukan dengan memberi materi bentuk gelombang serta bagaimana merangkai agar gelombang didapat melalui alat ukur oscilloscope.

The plasma polymerization replica method and its apparatus have been devised by Tanaka (1-3). We have published several reports on its application: surface replicas of biological and inorganic specimens, replicas of freeze-fractured tissues and metal-extraction replicas with immunocytochemical markers.The apparatus for plasma polymerization consists of a high voltage power supply, a vacuum chamber containing a hydrocarbon gas (naphthalene, methane, ethylene), and electrodes of an anode disk and a cathode of the specimen base. The surface replication by plasma polymerization in negative glow phase on the cathode was carried out by gassing at 0.05-0.1 Torr and glow discharging at 1.5-3 kV D.C. Ionized hydrocarbon molecules diffused into complex surface configurations and deposited as a three-dimensionally polymerized film of 1050 nm in thickness.The resulting film on the complex surface had uniform thickness and showed no granular texture. Since the film was chemically inert, resistant to heat and mecanically strong, it could be treated with almost any organic or inorganic solvents.

Introduction: The co-authors provide an overview of the main types of wind turbines and power generators installed into wind energy devices, as well as advanced technological solutions. The co-authors have identified the principal strengths and weaknesses of existing wind power generators, if applied as alternative energy sources. The co-authors have proven the need to develop an algorithm for the selection of a wind generator-based autonomous power supply system in the course of designing windmill farms in Russia. Methods: The co-authors have analyzed several types of wind turbines and power generators. Results and discussions: The algorithm for the selection of a wind generator-based autonomous power supply system is presented as a first approximation. Conclusion: The emerging algorithm enables designers to develop an effective wind generator-based autonomous power supply system.

The role of the power supply device is to produce, process and distribute energy sources. Telecommunication equipment can only operate if it has continuous supply. Therefore, to maintain the continuity of the supply, a UPS (Uninterruptable Power Supply) device system is needed so that the supply to the Essential Load device will remain available so that continuity will be maintained. This research designs and proposes how a series of automatic redundant switch systems on UPS to ensure the availability of power supply for the main equipment of telecommunications systems. The Auto switch circuit is designed to have 3 (three) working stages which will trigger the relay driver as control circuit, namely the normal working condition of the contactor input K1 is present, the input condition is zero (lost), and the input condition is present. This system can automatically supply power to telecommunications equipment.
