Tri-M Engineering V5SC-SER

Introduction

The V5SC is a high performance DC-to-DC 35 watt converter that supplies +5V. The V5SC also includes a flash based microcontroller that supplies advanced power management, smart battery charger and an RS232 serial port. The V5SC is designed for low noise embedded computer systems, has a wide input range of 6-40V(>6:1) and is ideal for battery or unregulated input applications. The V5SC is specifically designed for vehicular applications and has heavy-duty transient suppressors (6000W) that clamp the input voltage to safe levels, while maintaining normal power supply operation.

The V5SC is a state-of-the-art mosfet based design that provides outstanding line and load regulation with efficiencies up to 95 percent. Organic Semiconductor Capacitors provide filtering that reduces ripple noises below 20mV. The low noise design makes the V5SC ideal for use aboard aircraft or military applications or wherever EMI or RFI must be minimized. A constant off-time current-mode architecture regulator provides excellent line and load transient response for the +5VDC output.

The V5SC has a built-in 750mA-Hr 8.4V NiMh battery that is re-charged by the V5SC battery charger. The V5SC also supports external battery packs such as the BAT104-NiMh, or a non-PC/104 pack that is wired to the Battery Connector CN1. The V5SC utilizes a multi-stage charging for both the built-in batteries and the external batteries. The V5SC provides up to four stages of battery charging and can charge Lead-Acid, NiCd, and NiMh batteries and is also SMBus level 3 compatible. Charge
currents are up to 1.5A, and battery charging voltages from 9.5 to 19.5V.

The V5SC has advanced power management functions that allows timed on/off control of the V5SC, notification of changes to main power and changes in the battery status. For example, the V5SC can be programmed to power off the outputs in 60 seconds, and then turn on again 12 hours later.

The V5SC size is 3.55 x 3.775 inches, which is the same size as the PC/104 standard, and has the same mounting holes pattern as the PC/104 standard. However, the V5SC does not supply the PC/104 bus connectors. (For a PC/104 fully compliant power supply, please see the Tri-M Engineering HESC104.) All generated voltages are provided to screw terminals. The RS232 serial port is provided on a 2x5 row pin header.

The V5SC can be configured to meet almost any power supply and battery charging need for embedded applications, whether that be a simple +5V application, or providing power for back lighted LCD panels, or a full UPS (un-interruptible power supply configuration).

A range of battery packs are available. For further details click here.

Why choose a Tri-M power supply?

Tri-M power supply units use the highest quality components, which is why they are capable of operating as standard from -40 to +85°C. The heavier components are held to the board by straps so that in extreme heavy vibration environments, the components won't move (which in inferior products would eventually cause joint failures where components are continuously moving).
