R-78Txx-1.0 Series Switching Regulators (non-isolated)
The R-78T is a switching regulator with a wide input voltage range and a low profile SMD package. Three output voltages are available as standard: 3.3V, 5V and 12V. Due to the 1.5A start-up overload capability, the R-78T can be used to replace 1A or 1.5A regulators in many applications. These modules come with three different styles to be pin-compatible with existing solutions, but at a lower cost.
- Efficiency up to 95%, no need for heatsinks
- Industry standard pin-out
- 1.5A start-up overload capacity
- Non-isolated regulator, very low standby current
- Wide input range (7V -74VDC)
- Short circuit protection
- Fixed switching frequency (250kHz), shielded magnetics

AC/DC Converters
AC/DC-Power Supplies provide DC-Voltage to generations of electronic designs. Since the introduction of the EuP-Directive (energy saving products) in January 2010 the focus is on high efficiency. Particularly electronic devices with a standby- function require a small power supply to meet this directive. The modules of our AC-family provide 1 to 960 Watts power. They feature a high packing density, low no-load current and have an MTBF guaranteeing 40 years of continuous operation.
