Frequently Asked Questions - LDR-075 Nexa

What is the Nexa LDR-075 regulator used for?

The Nexa LDR-075 is a voltage regulator designed to stabilize the voltage supplied to your electronic devices, protecting them from voltage fluctuations and surges. It is ideal for use with computers, TVs, and other sensitive equipment.

How do I install the LDR-075 regulator?

Installation is simple: plug the regulator into a wall socket, then plug your device into the regulator. For wall-mounting, use the keyhole slots on the back. Ensure the regulator is placed in a well-ventilated area away from moisture.

What is the maximum power rating of the LDR-075?

The LDR-075 has a maximum output current of 10 A at 220V, which corresponds to a maximum power of 2200 VA (volt-amperes). Do not exceed this rating to avoid overload.

Does the LDR-075 protect against power surges?

Yes, the LDR-075 includes built-in surge protection that absorbs voltage spikes and protects connected devices. It also offers overload and short-circuit protection.

Can I use the LDR-075 with a refrigerator or air conditioner?

The LDR-075 is recommended for electronics such as computers, televisions, and audio systems. For high-inductive loads like refrigerators or air conditioners, a dedicated voltage stabilizer with higher rating is recommended.

How can I tell if the regulator is working correctly?

The front panel has LED indicators: a green light indicates normal operation, a red light may indicate overload or fault. If the red light stays on, check the load and reduce it if necessary.

What should I do if the regulator stops working?

First, check the main power supply and the connected device. If the regulator still doesn't work, the fuse may be blown. Replace the fuse with the same type (F 10A). If problems persist, contact a qualified technician.

Is the LDR-075 compatible with 110V systems?

No, the LDR-075 is designed for 220-240V AC systems (50/60Hz). Using it on 110V may cause malfunction or damage. Check your local voltage before use.

How do I clean the LDR-075?

Disconnect the regulator from the power source. Wipe the exterior with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. Ensure vents are free from dust.

Does the LDR-075 have a warranty?

Yes, the Nexa LDR-075 comes with a 2-year manufacturer warranty against defects in materials and workmanship. Keep your purchase receipt as proof.

ENGLISH

Dimmer receiver for permanent installation with adjustable minimum brightness. Suitable for LED strips and LED fixtures for constant voltage (built-in current limitation) of 12-24V.

SAFETY

Read through all of the instructions first. Call in a professional if necessary. Nexa cannot be held liable if the product is used for any purpose other than the one for which it is designed, or if there is failure to comply with the instructions. Never connect bulbs or equipment exceeding the receiver's maximum stated load – this could lead to faults, short-circuiting or fire. Do not attempt to repair the product. The product contains no repairable parts.

INSTALLATION

Connect the positive conductor from the voltage source (AC/DC adapter) to + and the negative conductor to - on DC in, the load's positive conductor + and negative conductor to - on DC out on the LDR-075.

LINKING

1. Power up the LDR-075

2. Press the learn button, the LED indicator will start to flash

3. Press the "ON" button for the selected channel on a System Nexa transmitter within 15 seconds

LINKING CONFIRMATION

The LED indicator lights steadily, if there is a bulb connected to the receiver it will flash twice.

DELETING A MEMORY SLOT

1. Press the team button

2. Press the "OFF" button for the selected channel on a System Nexa transmitter within 15 seconds

DELETION CONFIRMATION

The LED indicator lights steadily, if there is a bulb connected to the receiver it will flash twice.

DELETING ALL MEMORY SLOTS.

1. Press and hold down the learn button for 6 seconds, the LED indicator starts to flash rapidly

2. Release the learn button and then briefly press it again.

CONFIRMATION OF THE DELETION OF ALL MEMORY SLOTS

The LED indicator lights steadily, if there is a bulb connected to the receiver it will flash twice.

MEMORY

The LDR-075 has 6 memory slots which means that it can be controlled by up to six transmitters at the same time.

DIMMER SETTINGS

There are a total of four levels for lowest dimmer level where 4 is the lightest and 1 the darkest. The receiver is supplied set to the highest level (4).

SET THE LOWEST DIMMER LEVEL

1. Light the connected lamp using the transmitter

2. Press the training button twice. The LED indicator starts to flash and the connected lamp dims to the lowest level currently set

3. Press the 'OFF' button for the selected channel on the

transmitter to lower the level one step and "ON" to raise the level one step

1. Press the training button twice to confirm the selected dimmer level

If the connected bulb starts to flicker or goes out completely, go back one step in the lowest dimmer level settings.

SETTING THE LOWEST DIMMER LEVEL CONFIRMATION

The LED indicator lights steadily. If there is a bulb connected to the receiver it will flash twice.

CONTROL

The receiver can be controlled in a number of ways.

1. Using a trained System Nexa remote control

2. Using other trained System Nexa transmitters

3. Using a Nexa Bridge

OTHER INFORMATION

Range indoors: up to 30 m (optimal conditions). The range is very dependent on local conditions, if there is metal in the vicinity for example. The thin metal coating in low emissivity energy glass has a negative effect on the range of radio signals for example. There may be restrictions on the use of the unit outside the EU. If appropriate, you should check that the unit complies with local regulations. Max. load: Never connect bulbs or equipment that exceed the maximum load of the receiver. This could lead to faults. short-circuitting or fire.

Life-support equipment: Never use Nexa's products for life-support equipment or other devices where faults or interference could have life-threatening consequences.

Interference: All wireless units can suffer from interference that can affect performance and range. Because of this, the minimum distance between two receivers should be at least 50 cm

Repair: Do not attempt to repair the product. It does not contain any repairable parts.

Watertightiness: The product is not waterproof. Make sure it remains dry at all times. Damp will cause the internal electronics to corrode and this could lead to short-circuiting, faults and a risk of electric shock.

Cleaning: Clean the product using a dry cloth. Do not use chemicals, solvents or strong cleaning agents.

Environment: Do not expose the product to intense heat or cold as this could damage or shorten the service life of the electric circuits.
