RLP Series Rack Mount Power Supply, Input 110/220VAC, Output 22-29VDC, 20A

RLP Series Rack Mount Power Supplies

Premium Features

- All RLP Series power supplies are enclosed in a ventilated, gold irridite aluminum chassis.

- Front panels are powder coated aluminum with cutouts for rack mounting.

- Output connections are 1/4'' threaded studs with nuts.

- Lightweight, corrosion resistant, and excellent heat dissipation.

- Large scale Volt/Amp meter with selector switch and front-mounted ON/OFF switch. A charge status LED is provided when optional charger features are included.

- AC input voltage is automatically selected from 90~264 VAC / 50~60Hz and provides stable input when AC main power fluctuates. This is excellent for domestic and export sales to countries with older power grids. Models with smart charging (SC option) must be manually set to either 110 or 220 position. SC selector switch is on side of cabinet. No disassembly required.

- PFC (power factor correction) - a feature that only applies to AC circuits. It is the ratio of real power (watts) delivered to apparent power VOLT AMPS (VA) or Kilo-volt amps (KVA). In AC circuits, the voltage is a sine wave and the current (amps) is also a sine wave. For maximum power to be delivered, the two sine waves must be in correct phase or ``lock step.'' If the two are not in phase, the AC voltage will peak before or after the AC current. This out-of-step condition will reduce the real power that can be delivered to and used by the load. The ratio of real to apparent power is the POWER FACTOR which is expressed in a decimal or a percentage. If the real power is 70 watts, but the V/A is 100, the PF is 0.7 or 70%. For example, an incandescent lamp has a PF of .97 or better. An AC motor is typically 0.75 to 0.8. A low PF will cause excessively high current (amps) and heating of the load. Power factor correction maintains a high PF allowing more efficient use of electricity, resulting in lower power costs and longer component life.

- Remote Sensing - Regulated power supplies like the RLP series can sample the DC output voltage at the load and feed it back to the internal reference voltage of the power supply. The ``regulator'' adjusts the output voltage up or down as needed to compensate for line (voltage) loss between the output of the power supply and the input of the load, keeping the load input voltage constant. ``Line loss'' is a major consideration for installers and operators whose systems contain equipment with voltage sensitive microprocessors where DC voltage fluctuation can scramble programmed codes and frequencies.

- Remote Control - Remote control is the ability to bring the RLP series power supply ``on-line'' from another location, either automatically or by manual control using low level signaling, typically 5 volts (TTLogic level).

- Safety Approvals - The power modules used in the RLP Series are UL Recognized for USA and Canada. They also have TUV (Germany) and CE (Europe) safety approvals, making them International spec compliant.

Factory Installed Options

- Battery Back-up (BB) - Battery back-up system that includes diode isolation.

- Smart Charging (SC) - Module that monitors batteries for optimal charging and maintenance, extending battery life. Recommended for Deep Cycle or Gel Cell batteries. Polarity Protected.

- Low Voltage Disconnect (LVD) - Disconnects battery at an adjustable voltage to eliminate battery damage due to over discharging. Protects equipment that is sensitive to low voltage during battery operation. Disconnect range is 10.5~12 VDC for 12 volt systems, 21~24 VDC for 24 volt systems, and 46~48 VDC for 48 volt systems. Manual battery disconnect switch included.
