Product Usage Instructions

Before installing the STETSOM power supply/charger, please ask the store where the installation was carried out or contact the customer service for any doubts.

Dicas de carregamento
The STETSOM power supply/charger comes with three modes of operation that can be set using the selection key on the side of the product.

Charging Modes
The three charging modes include:

  1. SLOW: This mode charges the batteries slower, limiting the current up to 8A, which prevents overcharging and overheating of the batteries.
  2. FAST: This mode charges the batteries faster, providing a current up to 25A, which is indicated when the batteries are discharged and there is little time to charge them.
  3. FULL: This mode provides the maximum source current (50A) and can be used to charge multiple batteries or to power amplifiers and other systems.

Always prefer slow-charging as it provides less wear on the batteries, preserves their performance, and increases their useful life.

Voltage Selector Key
The voltage selector key allows you to toggle the voltage at which the source will operate. The four voltage options include:

  1. 12.6V: Sets the supply voltage from the source to operate continuously at 12.6V.
  2. 13.8V: Sets the supply voltage from the source to operate continuously at 13.8V.
  3. 14.4V: Sets the supply voltage from the source to operate continuously at 14.4V.
  4. 15.4V: Sets the supply voltage from the source to operate continuously at 15.4V. This mode is recommended for charging stationary batteries, using it on ordinary lead-acid batteries can permanently damage them.

15.4V Button
The 15.4V button sets the supply voltage from the source to operate continuously at 15.4V. This mode is recommended for charging stationary batteries, using it on ordinary lead-acid batteries can permanently damage them. In normal operation without deep discharge, stationary batteries can be charged in the same way as conventional lead-acid batteries, but when there is deep discharge at the end of the normal cycle, a voltage of 15.4V should be applied for a certain time. Each manufacturer determines what this time should be, so please refer to your battery manual to find out the best charge cycle for your stationary battery.

Introduction

Thank you for choosing a STETSOM product! Our new line of power supplies/chargers provide high performance and efficiency thanks to high- quality components and technologies developed for battery management and charging.

Before installing
Read this manual carefully before using the product.

  • All connections must be made with the product OFF.
  • Always use cable sizes recommended by the manual. This guarantees maximum security for your installation and the perfect functioning of the product.
  • Only use sockets and extension cords compatible with the current consumption of the source. Using poorly installed, poorly sized, or even defective outlets can damage the product or offer risks.
  • The source has an automatic bivolt circuit (127/220Vac).
  • Carry out the installation in a firm, ventilated and dry place.
  • Never handle the product with wet hands, barefoot or attempt to repair it. Internal components operate at high voltage and pose a risk of electric shock.
  • Installation must be done by a qualified professional.

In case of doubt, ask the store where the installation was carried out or contact our Customer Service: +55 18 2104 9412.

  1. AC POWER CONNECTOR: Connect to a compatible outlet for product operation. Do not use adapters or bend the cord, as this may reduce efficiency or cause it to malfunction.

  2. DC OUTPUT CONNECTOR: Connect to the battery terminals through cables with appropriate gauges, following the polarities indicated on the product. Never reverse the polarities.

  3. ON/OFF KEY with LED (POWER/PROT): The button has two LED’s that indicate its operation:
    RED LED: On when source is energized and in standby (OFF) or when triggered the protection system (PROT).
    BLUE LED: Indicates that the product is energized and in operation (ON ).STETSOM-50A-Power-Supplies-Chargers-02

  4. MODE SELECTOR KEY: Allows switching between source charging modes (SLOW, FAST, and FULL).

  5. CHAVE SELETORA DE TENSÃO: Allows selection of the source’s operating voltage.

  6. 15.4V BUTTON: This key activates the voltage mode at 15.4V. It is recommended for charging stationary batteries, using it on ordinary lead acid batteries can damage them permanently. When active, a GREEN LED on this button will remain lit even when the product is in STAND-BY for easy viewing.

Operation Modes
The power supply has operation modes that can be configured using the selection key on the side of the product.

CHARGING MODES:
Each position of the key represents a charging mode.

This mode allows slower charging of the batteries, limiting the current up to 8A. This prevents overcharging and overheating of the batteries, increasing their useful life and preserving their maximum performance for longer.

This mode allows fast charging of the batteries, providing current up to 25A. It is indicated when the batteries are discharged and there is little time to charge them.

This mode provides the maximum source current (50A). This mode can be used to charge multiple batteries or to power amplifiers and other systems..

Always give preference to slow-charging, it provides less wear on the batteries, preserving their performance and increasing their useful life.

VOLTAGE SELECTOR KEY:
Allows you to toggle the voltage at which the source will operate.

12. 6 V: Sets the supply voltage from the source to operate continuously at 12.6V.

13.8V: Sets the supply voltage from the source to operate continuously at 13.8V.

14.4V: Sets the supply voltage from the source to operate continuously at 14.4V.

3 15.4V BUTTON:
This button sets the supply voltage from the source to operate continuously at 15.4V. When this switch is pressed (on), the button’s GREEN LED will remain lit even with the product in STAND-BY for easy viewing. This mode is recommended for charging stationary batteries, using it on ordinary lead-acid batteries can permanently damage them.

In normal operation without deep discharge, stationary batteries can be charged in the same way as conventional lead-acid batteries, but when there is deep discharge at the end of the normal cycle, a voltage of 15.4V should be applied for a certain time. Each manufacturer determines what this time should be, so please refer to your battery manual to find out the best charge cycle for your stationary battery.

Smart Cooler
To offer more security and better performance, the source has the Smart Cooler feature. It consists of intelligent temperature monitoring, controlling the rotation of the Cooler according to the need, avoiding the overheating of the power supply and providing a quieter operation, preserving its performance and increasing its useful life.

Charging tips
For a good result, it is recommended that the current applied does not exceed 10% of the battery capacity.

  • Safe charging: Use the SLOW charge mode to provide a deeper charge and increase the lifetime of the battery.
  • Battery Bank: If the battery bank totals 250A, to current of 25A is now recommended for slow charging, equivalent to 10% of the battery capacity.
  • Charged battery: When the voltage is 14.4V and the current is less than 1%of the battery capacity, it is charged.
  • Monitoring: As the power supply has no voltage/current display, a voltmeter and an ammeter are needed to monitor this process.
  • Best results: It is recommended to keep the battery powered at 14.4V for another 8 hours after reaching 1% of battery capacity.

Protections
When a protection is triggered, the power supply will shut down and the LED on the POWER/PROT button will light red. Check the cause of the problem and turn on the power supply.
