The production processes of many enterprises imply the maintenance of constant stable communication between the departments of the designer and technologist with the workshops in which the direct manufacture of products is carried out. Specially created for these purposes stationary loudspeaker PGS-10 device is optimal for this task:
- Robust die-cast aluminum housing
- Simple construction diagram of the device.
- Direct connection to 220 V.
- Low sensitivity to voltage surges in the network (from -15 to + 10%).
- Possibility of connecting from 2 to 10 devices simultaneously to a single line.
Devices can be installed (securely fixed) both horizontally and vertically. Designed for work in heated industrial premises with normal (permissible) air humidity.
Features of the device diagram
The main purpose of the PGS-10 device is to efficiently transmit an audio signal (spoken speech) in a speakerphone format. This technical parameter is provided in full:
- An amplifier for receiving a signal with a frequency of 400 to 4000 Hz, which is assembled in a two-stage circuit using transistors.
- Signal transmission amplifier with a capsule differential electromagnetic type.
- The power supply is a power transformer with silicon diodes installed in a bridge circuit.
The principle of operation of the "Manual" device. Transmission and reception of information is carried out by pressing the corresponding button located on the body. The total harmonic distortion of the signals received and sent by the amplifiers is no more than 9%, which is a good indicator for ensuring high-quality intelligible communication.
You can get more complete information and order the required number of sets of loudspeaker devices PGS-10 using the website of the company that supplies this type of equipment directly from manufacturers. Products are available in stock and are sent to the customer after the purchase, which can be made online.
