• Жогорку ток кубаттуулугу: Provides an intermittent maximum output current of up to 30A.
• Noise Offset Function: Helps to mitigate switching noise by shifting it to another frequency.
• LCD дисплей: A backlit LCD provides real-time monitoring of output voltage жана ток.
• Интегралдык муздаткыч желдеткич: Forced air cooling prevents internal overheating during operation.
• Комплекстүү коргоо: Includes short-circuit protection, automatic current limiting (within 30A), and overvoltage protection to ensure user and device safety.
• Компакт дизайн: Measuring 155 (W) x 70 (H) x 205 (D) mm and weighing approximately 1.5 kg, it is designed for portability and space efficiency.
• Versatile Output Terminals: Features banana safety sockets (5A MAX) on the front panel and ground-type screw terminals (30A MAX) on the rear panel.

2. Коопсуздук нускамалары

Please read and understand all safety instructions before operating the Jesverty SPS-1332 power supply. Failure to follow these instructions may result in electric shock, fire, or damage to the unit or connected equipment.

• Кубат булагы: Connect the unit only to an AC power source within the specified voltage and frequency range. Ensure the power outlet is properly grounded.
• Вентиляция: Do not block the ventilation openings. Ensure adequate airflow around the unit to prevent overheating. The integrated cooling fan requires clear space to operate effectively.
• Курчап турган чөйрө: Operate the power supply in a dry, well-ventilated area, away from direct sunlight, heat sources, and moisture. Avoid operating in environments with excessive dust or corrosive gases.
• Байланыштары: Ensure all connections are secure and correct before applying power. Do not exceed the maximum current ratings for the output terminals (5A for front banana sockets, 30A for rear screw terminals).
• Ички мүмкүндүк: в ачпагылаasing of the power supply. There are no user-serviceable parts inside, and opening the unit voids the warranty and exposes you to dangerous voltages.
• Суюктук менен байланыш: Keep the unit away from liquids. If liquid enters the unit, immediately disconnect power and have it inspected by qualified service personnel.
• Ашыкча жүктөн коргоо: The unit features automatic current limiting and short-circuit protection. However, avoid intentionally short-circuiting the output or drawing excessive current, as this can still cause damage over time.
• Страховка: The unit contains a fuse for protection. If the fuse blows, it indicates an internal fault or severe overload. Replacement should only be done by qualified personnel with a fuse of the correct type and rating.

3. Орнотуу нускамалары

Follow these steps to set up your Jesverty SPS-1332 power supply:

3.1 Таңгактан чыгаруу жана текшерүү

1. Кубат булагын таңгагынан этияттык менен чыгарыңыз.
2. Inspect the unit for any signs of physical damage. If damage is found, do not attempt to operate the unit and contact your supplier.
3. Бардык аксессуарлар бар экенин текшериңиз.

3.2 Орнотуу

• Кубат киргизүү: Connect the provided AC power cord to the power input socket on the rear panel and then to a grounded wall outlet.
• Чыгуу туташуулары:
  • Front Panel (OUT- / OUT+): Use for loads requiring up to 5A. Connect banana plugs to the red (positive) and black (negative) safety sockets.
  • Rear Panel (OUT 13.8V MAX 30A): Use for loads requiring up to 30A. Connect wires to the red (positive) and black (negative) screw terminals. Ensure connections are tight.
• Жер терминалы: The rear panel also features a ground-type terminal for additional grounding if required by your application.

4. Иштөө нускамалары

This section details how to operate your Jesverty SPS-1332 power supply.

4.1 Күйгүзүү/өчүрүү

1. Ensure all connections to your load are correct and secure.
2. Flip the КҮЙГҮЗҮҮ/ӨЧҮРҮҮ switch on the front panel to the 'ON' position. The LCD display will illuminate.
3. To power off, flip the КҮЙГҮЗҮҮ/ӨЧҮРҮҮ 'OFF' абалына которуу.

4.2-томtage Тууралоо

Image 4.1: Output Voltage Adjustment Method

The SPS-1332 offers two voltage modes:

• Fixed 13.8V Output: коюңуз ТОМTAGE ADJUST knob to its center position (indicated by a detent or marking). The output will be a stable 13.8V DC.
• Variable 9-15V Output: айлантыңыз ТОМTAGE ADJUST knob clockwise to increase the voltage or counter-clockwise to decrease it. The output voltage can be adjusted continuously between 9.0V and 15.0V. Monitor the LCD display for the current output voltage.

4.3 Noise Offset Function

The NOISE OFFSET knob allows you to shift any potential switching noise to a different frequency, which can be beneficial for sensitive radio equipment. Rotate the knob to find a setting that minimizes interference in your application.

4.4 LCD дисплей

The LCD display provides real-time readings of the output voltage (V) and current (A). This allows you to monitor the power supply's performance and the power consumption of your connected device.

5. Техникалык тейлөө

Proper maintenance ensures the longevity and reliable operation of your Jesverty SPS-1332 power supply.

• Тазалоо: Disconnect the power supply from the AC outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners, solvents, or liquids.
• Вентиляция: Regularly check that the ventilation openings and the cooling fan on the rear panel are free from dust and debris. A clogged fan can lead to overheating.
• Сактагыч: Узак мөөнөткө колдонулбаганда, кубат менен камсыздоону салкын, кургак жерде, тике күн нурунан жана өтө температурадан алыс сактаңыз.
• Сактагычты алмаштыруу: The unit is equipped with a fuse for protection. If the power supply fails to turn on, the fuse may have blown. Fuse replacement should only be performed by qualified service personnel using a fuse of the exact same type and rating (e.g., F5A/250V). Incorrect fuse replacement can lead to fire or further damage.
