5. Instruccions de funcionament

5.1. Remote Sense

The remote sense function compensates for voltage drop on the cable between the power supply and the load, up to 0.3V. If the remote sense function is not required, +S and +V of the output terminal, as well as -S and -V, need to be connected as factory default setting.

Figure 5.1: Diagram showing connections for remote sense. Sense wires should be twisted in pairs to minimize noise pickup.

5.2. Voltage Ajust

El voltage can be adjusted using the built-in potentiometer (SVR) or via external voltage programació.

• Using SVR: Set DIP switch position-3 to ON. The output voltage can then be trimmed by SVR.
• Vol. De sortidatage Programació: Set DIP switch position-3 to OFF. The output voltage can be trimmed from 20~120% of the nominal voltage aplicant un volum externtage entre PV+ i PV- a CN313 o CN314.

Figure 5.2: Diagram illustrating voltage adjustment connections and a graph showing output voltage per centtage versus external voltage (VDC).

5.3. Ajust de corrent

The output current can be adjusted for overload protection (OLP) or constant current level programming.

• Default Overload Protection (OLP) Value: Set DIP switch position-2 to ON. The output current is set to its default value.
• Constant Current Level Programming: Set DIP switch position-2 to OFF. The constant current level can be trimmed from 20~100% of the rated current by applying an external voltage entre PC+ i PC- a CN313 o CN314.

Figure 5.3: Diagram illustrating current adjustment connections and a graph showing constant current level percentage versus external voltage (VDC).

5.4. Overload Protection (OLP) Mode

The RST-5000 offers two modes for overload protection:

• Continuous Constant Current Mode: Set DIP switch position-1 to ON. The RST-5000 will work in continuous constant current mode when the output is overloaded and the output voltage és superior al 50% del volum de sortida nominaltage.
• Delay Shutdown Mode: Set DIP switch position-1 to OFF. The RST-5000 will shut down after 5 seconds of constant current operation when the output is overloaded or short-circuited.

5.5. Control remot ON-OFF

The power supply can be turned ON or OFF using the "Remote ON-OFF" function. Refer to the table below for control logic.

Table 5.1: Remote ON-OFF Control Logic.

Figure 5.4: Diagram showing connections for remote ON-OFF control.

5.6. Sortida de senyal d'alarma

There are four alarm signals on CN315, and each signal can select two types of output circuit.

• Sortida de contacte de relé: (OTP1-GND), (DC-OK1-DC-OK1-GND), (AC-FAIL1-GND, AC-FAIL1), (FAN-FAIL1-GND, FAN-FAIL1). Normally open contact "Short" when the alarm arises. Relay contact rating (maximum) is 30V/1A resistive.
• Sortida de col·lector obert: (DC-OK2-GND, DC-OK2), (AC-FAIL2-GND, AC-FAIL2), (OTP2-GND, OTP2), (FAN-FAIL2-GND, FAN-FAIL2). An external voltage source is required for this function. The maximum sink current is 10mA and the maximum external voltage és 20V.

Figure 5.5: Diagram illustrating the connections for alarm signal outputs, including relay contact and open collector types.

5.7. Compartició actual

The RST-5000 has a built-in active current sharing function and can be connected in parallel, up to 4 units, to provide higher output power. The voltage difference among each output should be minimized (less than 0.2V). The total output current must not exceed the value determined by the following equation:

Maximum output current in parallel operation = (Rated current per unit) × (Number of units) × 0.9

When the total output current is less than 5% of the total rated current, or 5% of (Rated current per unit) × (Number of units), the current shared among units may not be fully balanced.

Figure 5.6: Diagram showing how to connect multiple RST-5000 units for active current sharing. +S, -S and CS+, CS-, RC+ and RC- are connected mutually in parallel.

• Quan s'utilitza la funció de detecció remota en paral·lel, el cable de detecció només s'ha de connectar a la unitat mestra.
• Els cables de la funció de detecció remota s'han de mantenir com a mínim a 30 cm dels cables d'entrada.

8. Manteniment

The RST-5000 series power supply is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.

• Neteja: Ensure the ventilation openings and fan are free from dust and debris. Use compressed air or a soft brush to gently clean the fan and heatsinks. Do not use liquid cleaners.
• Condicions ambientals: Verifiqueu que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats.
• Connexions: Periodically check all input and output connections to ensure they are secure and free from corrosion.
• Funcionament del ventilador: Listen for unusual noises from the fan, which could indicate a malfunction. The fan speed is controlled automatically based on temperature.

Avís: Always disconnect the AC input power before performing any maintenance or cleaning. Only qualified personnel should attempt internal repairs.
