Custom V/I Modifications

The product platform is incredibly flexible. Besides standard models, you can specify your own nominal voltage and current ranges. For example, if you needed to power a device at exactly 850VDC/100kW, we can engineer a unit with those ranges often without increasing lead time. Outputs up to 504kW are possible.

Where more functionality is required, an advanced LAB-HP version of the REC-HP-E is available. This model features a constant power mode and master/slave interface. An SD card slot is also possible with the advanced model, which allows specific output profiles to be implemented via simple text script. 

A wide range of three phase AC input options are available, meaning the units can be operated anywhere worldwide. A single phase input is possible up for 4kW and 5kW models on request (option /1P). 3kW models are built with a single phase input as standard.

Units can also be built with a user specified nominal DC input voltage in the range of 250VDC-750VDC ±10% (option /DC). For example, if you chose a 500VDC nominal then the rectifier would be built with an input range of 450VDC–550VDC.

Each unit has an RS-232, LAN and isolated analogue interface with switchable ranging as standard. If computer control is required then any combination of Integrated RS-485, GPIB and USB interfaces can be specified. ATE versions without a front panel are available, which are ideal for system integrations or remote applications.

Operating software is provided to set and monitor live values.

Passive Overvoltage Protection (Option /POP)

Transient suppression diodes are fitted within the unit across the output stage. This is used to detect and clamp transient voltage spikes.

Decoupling Diode (Option /DDS)

Built-in diodes in the positive lines to guard against the DUT's voltage being fed back to the PSU. Rated at 150% of the nominal output of the model. The decoupling diode is commonly used when the REC-HP-E is used to charge battery packs.

Freewheeling Diode (Option /FD)

Built-in diode arrangement across the output. This can permanently cycle the maximum current through the output stage. The main applications area is when the REC-HP-E is used for testing electric drives and inductive loads. The worst case fault condition of the DUT should be considered. If the DUT actively generates back towards the power supply and there is nothing else in circuit to sink the current then there’s the potential for voltage to rise above the nominal value and the rating of the DC filter which would cause damage.

Interlock AC or DC (Option /LOCK-AC or LOCK-DC)

This is an external option and provides a physical disconnection at either the AC input or DC output. The higher power systems may require additional rack space compared to standard units for either of these options. There is a choice of operating the hardware interlock via closing the contacts or applying an external voltage.

Safety Cover Set (Option /SC)

Metal covers for the input and output terminals with cable glands. Screws are M4 × 8mm.

Ruggedised Modifcations (Option /RUG)

Modifications can be made to the REC-HP-E to ensure suitability in harsh conditions by providing protection against shock and vibration. This is often ideal for companies who regularly need to move equipment to different sites, to mitigate the risk of any potential transit damage.

Conformal Coating of PCBs (Option /CC)

The PCBs of the units are coated with a solution to protect against environmental conditions such as condensing humidity, as well as providing resistance against salt moisture.  Option /CC can also be combined with /RUG. 

Each unit comes in a 19" rackmounting case as standard. If you require a desktop unit, 2U and 3U REC-HP-E models can be built without rackmounting flanges.

Units can be optionally treated to a laboratory rack or flight case integration. Having a power system mounted into a flight case on castors is often advantageous, especially when the equipment is needed at multiple sites. 

If you don’t have the time or resources to mount them into an enclosure, then we can do this for you. To view the possible integration options please view the separate rack enclosures datasheet.

Multiple power systems can be fitted into the same flight case. Door hangers are fitted for convenience. Existing ETPS systems can also be retrospectively integrated into new flight cases where requested.

If your test requirement is short term, we have a wide range of DC sources in our rental range.

A programmable DC output means that the unit can be honed to a specific application, ideal for many industrial processes such as electroplating and water treatment.
