Powersupplies for current lighting and the through put growth yield
wasn’t good. Wanted to control lighting, wanted the ability to control remotely and receive a report log for now errors. Product is in a highly
moist environment so need to be in an IP box.


Required a glass front for 2fold wifi controlled (metal box) gives the users an identification if there was a known error. Prototype first without controls – increased light out 20%
Then the second phased prototype created with full control, installed in Scotland increased light output 35%.


We allowed a 30% headroom, not putting any strain on the product. Each output to the light is fused so to limit the current to one device and reduces the risk of single point of failure.
RSP1600 MEAN WELL suitable due to its dimensions, power density, true power derations vs temperature, this is key due to the harsh environment moisture.

EV Charging Station Power Supply


Going green; Economic and environmental factors are the top reasons for considering electric-powered alternatives to vehicles. The MDR series provided a very suitable solution being incorporated into an electric vehicle charging station to power localised electronics, in this instance as a small form factor power supply.

The customer found it to be a very cost effective way of providing a high reliability and easily connectable unit which would apply (within the charging station) to installation in varying environments and locations. The high operating temperature (-20~+70°C) meant that the charging points are not prohibited to specific locations. Din rail mounting allowed the customer to design the internal electronics with a range of adaptable and easy mounting solutions for different variants of their modular electronic systems.

Testing Equipment Power Supply

Sunpower were selected to install testing equipment power supply for vehicle engines in the production line. A relatively small unit with a large current was required to power the controller running the whole operation, making the SP-500 ideal.

The SP-500 series is an enclosed unit offering 500W of power with protections including short circuit, and over load as well as a fixed switching frequency at 110KHz this unit is also ideal for applications such as electronic equipment, industrial automation and instrumentation.

Secure storage, charging and synchronisation of devices on demand

Staff and students in schools and other educational establishments frequently use Apple iPads and other tablet PCs, as do workers in offices, garages and most other enterprises.

The Challenge

To enjoy the maximum benefit from these devices with the least downtime, risk of damage or theft, and inconvenience, all users need easy access to a facility that provides secure storage, charging and synchronisation of their devices on demand.

One popular solution is a Charge and Sync Tablet Carry Case; this heavy-duty, reliable unit can store, charge and sync multiple devices simultaneously. The case is often powered by Sunpower Charge and Sync Tablet Carry Case Power Supplies; common choices are either a RSP-200-5 fanless power supply or the SP-200-5 fan-cooled version. Fan cooling means that the SP-200-5 can be built into enclosures with limited ventilation; accordingly, the Carry Case has been implemented using a wheeled flight case for rugged portability. The devices can be safely charged with the case’s lid closed for extra security.

The Solution

The power supply drives a USB distribution board, delivering up to 36 A. This allows charging of up to 16 tablets, supplying each with their maximum possible charging current of 2 A. The power supply’s output can be set to 5.2 VDC, to facilitate synchronisation as well as charging.

The Carry Case is compatible with the iPad as well as a large number of commercially available tablet PCs and mobile devices. Intelligent electronics ensure that any USB device can be charged at the same rate as from the original manufacturer’s charging unit. Connected devices can be mixed for charging; they do not have to be the same manufacturer or product type.


Other features of the SP/RSP-200 series include a universal AC input, built-in active PFC, Short Circuit, Over load, Over voltage, and Over Temperature protection, built-in cooling fan speed control, constant current limiting circuit and an optional remote On/Off control. A three year warranty is provided with all units.

Charging Locker Power Supplies

Keep your valuables safe whilst charging with Charging Locker Power Supplies

Schools and festivals don’t have much obviously in common. However most attendees at both these environments today share a dependence on mobile electronics from smartphones to laptops – and a need to keep them charged and running for extended periods. Mobile and permanently-installed charging lockers have become a practical and popular solution, as they offer an electrically safe and theft-proof charging and storage resource to a large number of users simultaneously. This has lead to an increasing demand for Charging Locker Power Supplies.

Educational administrators and festival organisers investigating these lockers for rent or purchase naturally want to offer the widest range of options to the largest number of users. One charging locker manufacturer has significantly improved their products’ ability to meet these goals by taking advantage of the high power density of Sunpower RSP-1000 power supply’s and many other features.

The RSP-1000’s wide 40 – 110% voltage trimming range was a key selection factor. Simple to set up using an external voltage source or resistors, it gives the charging lockers multipurpose capabilities without restriction to one particular laptop brand or voltage. The voltage adjustment feature means that the nominal 24 VDC output can be reduced right down to 9.6 VDC if required. Alternatively, the output could be set at 13.8 VDC to drive car charger sockets, allowing festival-goers to top up their mobile phones, PDAs and any other smart devices they would normally plug into a car charger.

The charging locker station allows up to 32 devices to be charged simultaneously, each within its own lockable charging and storage compartment. While this efficient packing density is attractive to operators, running 32 power cables in the limited space available, and connecting them to the single power source without a distribution box and voltage drop, presents a challenge. Fortunately, the RSP-1000’s positive and negative output connections mean that copper bus bars can be installed behind the lockers, with only very short cable runs from the bus bars to the smart device connectors. Voltage drops are nearly eliminated; any remaining error can be corrected by voltage adjustment. The power supply itself is also highly efficient, at up to 90%.

The RSP-1000’s output power remains consistent across most of the universal AC input voltage range. This allows the charging lockers to perform reliably in numerous locations with different mains voltages around the world. Two or even three PSU units can be connected in parallel both to increase power capacity and improve reliability through redundancy. As the power supplies feature active current sharing, this configuration is easy to set up. Additionally, operators can quickly and remotely spot any fault that does occur, using the monitoring software provided with the power supplies. The RSP-1000 also has built-in hardware protection from short-circuit, over load, over voltage and over-temperature conditions.

Other features of the 1U low profile RSP-1000 include a 5 V/0.5 A auxiliary output, remote sense, remote On/Off control and a DC OK signal. Additionally, it has constant current limiting, making it suitable for capacitive and inductive loads.
