User Manual for Stetsom Infinite Black Power Supply & Charger

Quick guide from the manual

The Stetsom Infinite Black series is a range of high-performance power supplies and battery chargers designed for intelligent battery management. These units feature automatic bivolt (127/220Vac) compatibility and multiple charging modes to optimize battery life and performance.

Product Overview

The unit features a front panel with the following controls and indicators:

• AC Power Connector: Connect to a compatible AC outlet. Avoid using adapters.
• LED Display: Shows real-time voltage and current information and allows configuration of programming modes.
• DC Output Connector: Connect to battery terminals using appropriate cable gauges. Observe correct polarity.
• ON/OFF Key (POWER/PROT): Turns the unit on/off. The internal LED indicates standby mode or active protection (PROT).

Charging Modes

The power supply offers three distinct charging modes:

• Fixed Voltage Mode: Allows selection of output voltage from 12.6Vdc to 14.4Vdc. Ideal for powering amplifiers directly without batteries or with batteries while playing sound.
• Smart Slow Charge (Slow SCS): Intelligently regulates voltage and current (5% to 20% of programmed current) to prevent overcharging and heating. Once 14.4V is reached, it maintains this for ~8 hours before entering float mode (13.8V).
• Smart Fast Charge (Fast SCS): Similar to Slow SCS but provides higher current (20% to 35% of programmed current). Ideal for quickly charging discharged batteries.

Installation

Installation must be performed by a qualified professional with the product turned OFF.

Simple Installation

Used to charge a battery bank and power sound equipment. Connect the positive and negative terminals of the power supply to the battery terminals using the recommended cable gauges.

Parallel Installation

When using two or more power supplies in parallel, use only the Fixed Voltage mode. All units must be configured to the same output voltage. Smart charge modes should only be used with a single power supply connected.

Installation as Power Supply Only

Used to power sound equipment without batteries. Ensure the total consumption of the equipment does not exceed the rated current of the power supply to avoid triggering protection.

Protections

If a protection is triggered, the unit will turn off and the POWER/PROT button LED will light up. Protections include:

• Internal AC input fuse: Protects against internal short circuits.
• DC output short circuit: Protects against short circuits and output overload.
• Low Voltage (Undervoltage): Protects if output voltage drops below 7.5Vdc.
• Temperature: Intelligent monitoring regulates operation based on temperature.

Technical Specifications

The Infinite Black series is available in 70A, 120A, 150A, and 200A models. All models feature automatic bivolt (127Vac/220Vac) input, 12.6V-14.4V DC output, and 90-95% efficiency depending on the model.

Warranty

Stetsom provides a 1-year warranty against manufacturing defects from the date of sale to the final consumer. Proof of purchase (sale note or warranty certificate) is required for service.
