Description

The TEPLOCOM ST series from BASTION CJSC (Rostov-on-Don, Russia) is a family of single-phase relay-type automatic voltage stabilizers designed to protect heating systems, gas boilers, and household appliances from power grid fluctuations. The series spans four power ratings — 222 VA, 555 VA, 888 VA, and 1515 VA — covering everything from a compact wall boiler to a multi-appliance utility circuit.

All models operate across a wide input voltage window of 145–260 V, delivering a stable 220 V output with ±8% accuracy through four regulation steps. A defining feature is BASTION's proprietary ZERO-CROSS technology: relay switching occurs precisely at the sine wave zero-crossing point, eliminating arc-induced contact wear and preventing distortion of the output waveform — a critical requirement for modern boiler electronics.

Microprocessor control governs all switching, and automatic protective shutdown triggers when output voltage falls outside safe bounds. The larger ST-1515 adds self-diagnostics, error indication, and ground integrity plus phase-sequence monitoring.

All models mount on the wall — smaller units accept a DIN-rail bracket (supplied), while the ST-1515 uses a three-point screw mount. Housing is rated IP20 for indoor installation.

The series carries full EAC certification (TR TS 004/2011, TR TS 020/2011, TR EAEU 037/2016), is listed in the Russian industrial goods registry under Government Resolution No. 719, and is backed by a 10-year extended warranty upon product registration.

Details & Equipment

Product Views

TEPLOCOM ST-222/500 — front view

The base model of the series in its compact 104×135×104 mm plastic housing (IP20), showing the LED status indicator and the output socket that accepts the boiler power plug directly.

Side profile with DIN-rail bracket

The DIN-rail mounting bracket ships in the box; it clips to a standard 35 mm rail for installation in distribution boards or dedicated enclosures alongside heating system components.

Wiring

Connection diagram — ST-222/500

The stabilizer installs in series between the building supply and the boiler: mains enters the input terminals and the boiler plug connects to the output socket, requiring no additional wiring tools beyond a screwdriver.

Features

🔄

ZERO-CROSS Switching

Relay steps switch at the exact zero-crossing of the voltage sine wave, preventing arc erosion on contacts and introducing no distortion into the output waveform — extending the life of boiler control boards and other sensitive electronics.

⚡

Wide 145–260 V Input Range

Operates continuously across a 115 V span — from severe grid sag at 145 V to surge peaks of 260 V — maintaining a 200–240 V output at normal grid voltages and holding output above 170 V even at extreme low-voltage conditions.

📊

Four Power Ratings

Available in 222 VA, 555 VA, 888 VA, and 1515 VA to match loads from a single wall-mounted gas boiler to multi-appliance circuits; all share identical protection technology and form factor logic.

🛡️

Automatic Protective Shutdown

Built-in undervoltage and overvoltage relay disconnects the load when output drops below 170 V ±3 V or exceeds 242 V ±3 V, safeguarding flame sensors, pumps, and boiler PCBs from damaging excursions.

🔧

Simple Installation

Compact wall-mount body with DIN-rail bracket included; the ST-1515 uses a three-point wall screw mount for larger installations. Connection is as straightforward as a power strip — no electrician required for basic setups.

🏭

Certified Russian Manufacture

Registered in the Minpromtorg industrial goods registry (PP No. 719) and certified to EAC standards TR TS 004/2011, TR TS 020/2011, and TR EAEU 037/2016; eligible for public procurement under national preference rules.

Buyer Benefits

Protects gas boiler electronics — flame sensors, PCBs, and circulators — from the voltage surges and sags that most frequently cause premature boiler failures.
145–260 V operating range provides reliable protection in rural, suburban, and industrial areas where grid quality is poor or unstable.
ZERO-CROSS technology eliminates relay contact arcing, giving the stabilizer a substantially longer service life than conventional relay designs without this feature.
Compact, lightweight enclosure (IP20) fits in boiler rooms, utility closets, and tight wall spaces without requiring a dedicated equipment cabinet.
10-year extended warranty (activated by product registration) delivers significantly lower total cost of ownership compared to competitors offering 2–3 years.
Minpromtorg registry listing (PP No. 719) qualifies the product for preferential treatment in Russian public tenders and public-sector procurement.
Negligible 6.4 mA no-load current draw ensures minimal standby energy cost during continuous 24/7 operation throughout the heating season.

Applications

Wall-mounted gas boilers (open and closed combustion chamber) with consumption up to 1515 VA Heating system automation equipment, circulation pumps, and zone controllers Residential apartments and cottages with unreliable or fluctuating grid supply Boiler rooms, utility rooms, and equipment closets in office and commercial buildings Small industrial and workshop machinery requiring stable single-phase 220 V supply Security systems, access control panels, and building automation controllers Small medical and laboratory equipment sensitive to voltage distortion Cottage associations and rural properties served by aging distribution infrastructure
