Relay Amplifier Device [RP-1251]

We will improve the transmission quality of the metal cable line (4-wire type) used for C-type train radio, aiming to stabilize the train radio system and enhance its reliability.

■□■Features■□■ ■The amplification circuit can compensate for bidirectional (up/down) line loss (up to 20dB in 1dB steps). ■The amplitude correction circuit allows for the correction of amplitude characteristics in both directions (up/down), with settings available in four stages, enabling a maximum correction of +12dB for an amplitude corresponding to a frequency of 3300Hz (equivalent to the press signal frequency) at 1kHz. ■The input and output impedance of the line is compatible with either 600Ω or 370Ω (configurable). ■The device can be powered by AC100V, DC24V, or DC48V. ■For AC100V power supply, rechargeable batteries can be installed (optional). ■The structure is a standard rack 1U unit (height 50mm), so it does not take up much space.
