BSG-26 SERIES

INSTRUCTION MANUAL

WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

GENERAL:

The BSG-26N and BSG-26P are Black Signal Generators which provide six (6) blackburst signal outputs. The outputs are driven from the same internal source to ensure system synchronization. The design of the units provides suitable operation for applications from complex total system timing to laying black on tape. The blackburst signal is digitally derived from a temperature compensated oscillator. These units provide a stable output and do not require any adjustments during operation. The outputs are present when power is applied.

Superblack operation is selective via J1. With J1 jumper shorted across pins 1 and 2, the module will produce superblack on all outputs. Superblack can be used when building a Multi-Pass special effect. The superblack signal, approximately -7.5 IRE, provides a noiseless background that can be laid down on the tape for this application.

The BSG-26N, NTSC version, provides outputs per RS-170A / SMPTE 170M standards. The BSG-26P, PAL version, provides outputs per CCIR 624-4 standards. Specifications are provided in the SPECIFICATIONS section.

POWER:

The BSG-26 Series accommodates a wide range of line voltage from 90 VAC minimum to 255 VAC maximum. The line frequency range is 50 to 60 Hz. The units utilize an IEC 320 inlet to accommodate the proper power cord set for the line voltage connectors used in any geographical area. The combination of the wide voltage range and universal inlet contributes to the diversity of applications where the BSG-26 will supply a dependable source of black signal. The module internally regulates the bus voltage to +5 VDC (U8) and -5 VDC (U9). Circuit protection is provided by an externally accessible fuse (Figure 1).

FRAMES:

The BSG-26 units are assembled in a stand-alone box. The metal enclosure provides desirable shielding from external EMI / RFI noise sources. See the section on SPECIFICATIONS for recommended operational conditions. The units are capable of rack mounting with the optional RMK-26 Rack Mount Kit. This 1RU rack mount does not require blank panels for unused portions. A total of three (3) Series 26 units may be mounted with a single RMK-26.

CONNECTIONS:

The connectors are located on the rear panel. BNC connectors are used for the six outputs. Each of the outputs are designed to drive a 75 Ohm load. The outputs must be terminated by a single end of line 75 Ohm termination to ensure proper signal level. Unused outputs do not require a 75 Ohm terminating resistor.

BSG26N specifications

The Sigma BSG26N is a robust and versatile inverter generator designed to cater to a range of power needs, from outdoor adventures to emergency backup situations. With a compact design and a lightweight build, it is an ideal choice for campers, tailgaters, and those who require a reliable power source in remote locations.

One of the standout features of the Sigma BSG26N is its powerful 2,600-watt output, which is sufficient to run several appliances simultaneously, including refrigerators, lights, and power tools. The generator provides a peak power capacity of 3,000 watts, making it suitable for starting larger equipment. This dual output capability ensures seamless functionality for both household and industrial requirements.

The BSG26N incorporates advanced inverter technology that produces clean and stable energy output, resulting in minimal Total Harmonic Distortion (THD). This characteristic makes it safe to power sensitive electronic devices such as laptops and smartphones without risking damage. With a noise level as low as 58 dBA, it operates quietly, making it perfect for use in residential areas or during camping trips.

The generator is equipped with an efficient fuel system that allows for extended run times. With a fuel tank capacity of 2.2 gallons, it can run for up to 10 hours at 50% load, providing users with uninterrupted power supply over long periods. This efficiency is further enhanced by its eco-mode feature, which adjusts the engine's speed according to the load demand, optimizing fuel consumption and reducing emissions.

Furthermore, the Sigma BSG26N is designed with portability in mind. It features a lightweight structure and built-in carry handles, making it easy to transport. The generator is also equipped with multiple output options, including two 120V AC outlets and a 12V DC outlet, allowing users to connect a variety of devices without hassle.

Safety is a priority for the Sigma BSG26N, which includes a low oil shutdown feature that automatically turns off the generator when oil levels are critically low, preventing engine damage. Additionally, it has a built-in circuit breaker to protect against overloads.

In summary, the Sigma BSG26N is a powerful and efficient inverter generator that combines portability, technology, and safety features, making it an excellent choice for anyone in need of reliable temporary or backup power. Its ability to deliver clean energy while maintaining user-friendly aspects positions it as a compelling option in the inverter generator market.
