HPT categoría de planar
The HPT series (Hybrid Planar Transformer) is able to manage power up to 3150W, with efficiency up to 99%, due to its design and its low losses. It is available with full-bridge and ZVT full bridge topology and it’s a specific solution for DC/DC transformers applications for 28V buses.
Key characteristics:
- High range of operating temperature from -40º C to 90º C, with heat sink dissipation, with effective temperature up to 125º C
- Storage temperature from -50º C to 170º C
- Operating frequencies up to 150KHz
Due to the advantages of this inductors, they are recommended especially for these applications: DC/DC converters of 28 V, inverter, DC/AC converter high voltage buses, electronic control unit (ECU), control unit.

Using an auto-transformer is always an economical solution when you need to step down the voltage from 230V to 120 V or vice versa, and the equipment already has a fully isolated transformer or when the components do not require an isolated transformer.
The toroidal construction of an auto-transformer offers important advantages in comparison with an E/I lamination core transformer, like smaller physical size and weight, 30-70% reduction (depending on secondary voltage) and very low magnetic strayfields. The auto-transformer can be mounted horizontally using a steel washer or our Poly-Mount, a plastic insert, or an epoxy potted center with a 1/4" mounting hole.

The intermediate battery charger range: Chargetec C300 and C400 series
The Chargetec C300 and C400 series of battery trip units provide a more comprehensive array of functions and alarms than those offered in the Economy range. This includes a microprocessor based, temperature compensated, and current limited charger with a wider range of alarms, including high volts, low volts, AC mains fail, and low battery voltage cut-off via the battery isolation MCB. The battery load test facility is now automatic. The standing load capability is increased over the economy trip unit to150watts. The metering is also increased over the economy trip unit to include a voltmeter, a charge / discharge ammeter and LED’s to indicate the alarm condition.
- Charger size: 300mA to 4A.
- Voltage range: 24, 30, 50 & 110v DC.
- Battery size: 5 or 8Ah (VRLA).
