RF power amplifiers

A media converter is used as a converter that converts one signal transmission medium into another. The data transmission medium means optical and copper cable. The scope of application – FastEthernet and GigabitEthernet protocols, STM-1 and STM-4. Media converters are characterized by a number of parameters, by setting that you can choose the optimal network equipment for solving a specific task. The possibility to control the device; Installation location; Properties of the optical receiver-transmitter; Supported transfer rate.

The module has a built-in autonomous temperature protection and RF transistor current protection. There is an input of external blocking of the RF path, which can be used as an input of amplitude modulation. MAG-1K0.LF modules are used to build all Plasma GK series RF generators with frequencies of 0.35...2.0 MHz.

A series of modern intelligent relay protection, automation and alarm units PARMA IED-EP+ is designed for use in networks with a voltage from 6 to 750 kV

XFP (10-Gigabit Small Form Factor Pluggable) is a protocol—independent hot-swappable optical transceiver, usually operating at 850nm, 1310nm or 1550nm wavelengths or wavelengths from the CWDM band at a speed of 10 gigabits per second in SONET/SDH, Fiber Channel, Gigabit Ethernet, 10 Gigabit Ethernet and other applications, including WDM channels.

Optical transceivers are in standard SFP metal cases with separate optical input/output for LC type connectors to transmit the signal over two optical fibres

Mathematical processing of the measurement makes it possible to determine and display on the indicator board the relative systematic change in frequency, the average relative value of the frequency difference, the RMS relative frequency deviation, the RMS relative two-sample frequency deviation.

Optical transceivers are available in 9-pin plastic cases with separate optical input/output for SC (FC) connectors

Optical transceivers are in standard SFP metal case with integrated optical input/output for SC,LC connectors for to transmit the signal over a single optical fiber.

PARMA UACHR 12 is designed to eliminate the shortage of active power in the network by automatically turning off consumers when frequency decreases, followed by automatic re-activation of previously disconnected consumers when frequency is restored, as well as to eliminate the shortage of reactive power in the network by disconnecting consumers when voltage decreases, followed by automatic re-activation of previously disconnected consumers when voltage is restored. PARMA UACHR 12 can perform the functions of dividing automation, be used at power plants and substations of power systems, as well as a device for local emergency automation of 0.4 kV networks as part of an automatic load control system. PARMA UACHR 12 is the first microprocessor-based frequency unloading device in Russia that has received a certificate of compliance with the requirements of the standard of the organization of JSC "SO UES" STO 59012820.29.020.003-2016 "Relay protection and automation.
