CBC Design

Our fully enclosed chargers are available in standard industrial configurations. Mild Steel Enclosure: Industrial grade mains cam switch, mains on led, mains and output fusing, top or bottom entry gland plates, quality moving coil ammeter and optional voltmeter. Systems are available in 6, 12, 24, 30, 48, 96, 110 & 220VDC with single, two or three phase inputs.

For more advanced and large system designs, we work closely with a leading manufacturer based in Northern Ireland who manufacture charging equipment to specification using CBC Design components and configurations.  Contact us by email via our website for more information.

As well as manufacturing enclosed charging systems we produce open chassis versions for installation into existing enclosures. Built to order, each system is bespoke to suit end customer requirements. 

Our High Voltage alarm relay measures the charger output and battery voltage and provides a local indication as well as double pole volt free relay changeover for remote scada purposes if it rises above an adjustable preset maximum value. Typically this alarm is used to ensure that  the batteries are not over charged due to a charging system faults or some other undesirable over voltage condition.  

The alarm plugs into a standard 11 pin relay socket and is available for 12, 24, 30, 48 and 110VDC applications. It can also be configured for other less popular voltage applications.

As well as charging batteries it is often essential to know what your cells are doing when mains power is unavailable. Our Low Voltage alarm relay measures the charger output and battery voltage and provides a local indication as well as double pole volt free relay changeover for remote scada purposes if it falls below an adjustable preset minimum value.  

The alarm plugs into a standard 11 pin relay socket and is available for 12, 24, 30, 48 and 110VDC applications. It can also be configured for other less popular voltage applications.

Our High-Low Voltage alarm relay measures the charger output and battery voltage and provides a local indication as well as two separate single pole volt free relay changeover contacts (one for high, one for low) for remote scada purposes if the voltage rises above or falls below an adjustable preset minimum and  maximum value. Typically this alarm is used where both high and low voltage fault detection is required using a single plug-in device.

The alarm plugs into a standard 11 pin or 8 pin relay socket and is available for 12, 24, 30, 48 and 110VDC applications.

The Charge Fail Alarm relay is available in two configurations. A type 1 which uses a current transformer to measure charging current, typically in thyristor based charging systems and type 2, which measure the output voltage from switch mode or linear charging systems on the anode of the isolating diode typically fitted between the positive charger output and the battery and load.

The unit plugs into a standard 11 pin relay socket and includes on-board leds and a double pole double through volt free relay contact. It is available in 12V, 24V 30V, 48V and 110V versions as standard. Other less popular voltage models are also available upon request.

Designed to measure both poles of the battery or dc power supply, the Earth Leakage Alarm Relay will respond to a negative or positive earth fault and the corresponding led on the front panel will illuminate. Following a short delay, the internal double pole relay with volt free changeover contacts trips to provide a remote warning signal.

The Earth Leakage Alarm Relay is capable of detecting earth faults on dc installation including batteries, chargers, rectifiers and transformer secondaries. 

Its is available in 12, 24, 30, 48 and 110V versions and other less popular voltage models upon request. It plugs into a standard 11 pin relay socket.

Our hall effect high current alarm relays are designed to monitor DC current and de-energise a double pole double throw volt free relay if the measured value rises above or falls below two pre-set (via adjustable potentiometers) current values.

Typical applications would include any DC powered assembly where high or low current indicates a fault condition with potentially dangerous consequences such as failure of control in a battery charging system, overload of a battery installation or power supply or loss of supply to a vital load. On-board Leds signify which condition has occurred.

The alarm plugs into a standard 11 pin relay socket and a separate PCB includes the hall effect current measuring sensor. Visit http://www.cbcdesign.co.uk/alarms/cr.html for more information

The 823 High-Low Voltage Alarm led Driver is a simple, inexpensive solid state electronic assembly designed to illuminate a pair of external warning leds if the measured voltage drops below or rises above two separate pre-set limits. The HLVI can also be used to sound buzzers. The low voltage detector includes a delay to prevent nuisance tripping in applications where short term (<60 seconds) loads are typically present.

The 823 is available in 6V, 12V or 24V versions. 

If you need an industrial grade inexpensive reliable device to light up an led to signify that a battery or DC supply voltage is low, our 722 or 822 series Low Voltage Led Drivers are a good solution. The 722 is the most basic model, switching an led on using an uncommitted transistor collector if the voltage drop below a preset (adjustable) value.  

Our 822 is a slightly more advanced model used in applications where short term loads will cause the voltage to fall before rising again and an alarm is not required unless the voltage drop is sustained over a longer period of time, typically 60 seconds or above.  The 822 is used in marine, audio and battery status monitoring applications . 

The 722 and 822 is available in 6V, 12V and 24V models.

The Battery Equaliser compensates for balance irregularities between series connected batteries and increases the capacity accordingly. In independent tests improvements of up to 40% were recorded using equalisers in automotive applications. Contact CamdenBoss on 01638 716101 for further information.

The 994VU-VT is a stereo VU meter assembly housed in an ABS enclosure designed to display a representation of the average value of a stereo audio input signal sourced from connected equipment including media streamers, CD players, tape decks, set top boxes and other media devices.

Two pairs of gold plated RCA connectors on the rear panel are used to connect the unit in series with the RCA connection between the source device and a suitable amplifier. An IEC connector is used to connect mains power to the device at any input voltage between 85VAC and 250VAC at 50 or 60HZ.
