Derating Curve

The derating curve illustrates the relationship between ambient temperature and the maximum load percentage the inverter can handle. For DC input voltage, specific derating is shown for 10Vdc, 20Vdc, and 40Vdc inputs across their respective operating ranges.

Ambient Temperature Derating: The inverter can operate at 100% load up to approximately 40°C. Load capacity decreases linearly from 40°C to 70°C, reaching about 50% load at 70°C.

DC Input Voltage Derating: Specific derating curves are provided for 12Vdc, 24Vdc, and 48Vdc input voltages, showing load capacity relative to input voltage levels.

Remote Control and Communication

Remote Controller (Accessory)

Optional remote controllers (IRC1, IRC2, IRC3) serve as monitoring and control units. They decode RS-232 signals from the inverter and display information on digital meters. LED indicators on the controllers show:

• Green LED: ON
• Orange LED: OFF
• Red LED: Abnormal Status
• Orange Flash LED: Power Saving Mode

RS-232 Communication

The inverter's internal data can be accessed via RS-232 communication. The required communication cable (RJ11-RS232) has order number DS-RJ11-RS232 and must be ordered separately.

Remote ON-OFF Control (Built-in)

The inverter features a built-in remote ON-OFF control via the remote port. A dry contact connection is used:

• Open connection: Power inverter ON (Normal work)
• Short connection: Power inverter OFF (Remote off)

DIP Switch Settings

The inverter's AC output voltage, frequency, and power saving mode can be adjusted using DIP switches (SW1-SW4) located on the panel. Factory settings are typically 110Vac/60Hz.

LED Status Indicators

The front panel includes LEDs to indicate the operational status:

Normal Work Status:

• Status LED: Green (Inverter OK)
• Remote LED: Orange (Remote off)
• Saving Mode LED: Orange (Saving mode)

DC Input Status:

• Green LED: Indicates normal voltage range (e.g., 12.5~15.5Vdc for 12V input).
• Orange LED: Indicates a warning voltage range (e.g., 11~12.5Vdc for 12V input).
• Red LED: Indicates a critical voltage condition (e.g., <11Vdc or >15.5Vdc for 12V input).

Load Status:

• Green LED: <40% load
• Orange LED: 40~80% load
• Red LED: >80% load

Abnormal Status Indications:

LED States: Light (On), Light off, Flash.
