Overview

PSC-160B-C is the CH1: 27.6V / CH2: 27.6V output model of this series: rated current CH1: 3.8A / CH2: 2A, rated power 160W, typical efficiency 90%.

PSC-160 series is a 160W AC/DC security power supply, allowing the universal input range between 90VAC and 264VAC and incorporating the built-in PFC function. In addition to the primary output, there is a charger output, with the smaller rated current, that provides the backup power supply application the security access systems require. PSC-160 delivers an efficiency up to 90%; it can operate with air convection under -20℃ through 70℃. This series is designed with thorough alarm features, including AC OK and battery low signaling; moreover, the relay contact is provided to facilitate users' system designs. PSC-160 is available in the PCB type or the enclosed type with L-Bracket and cover.

Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. Please refer to suggested Application 2.(2)、(3) in page 3.
6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can I use the PSC-160B-C for a 24V industrial control panel battery backup system?

It is designed for a 27.6V output rated 3.8A for the load plus a 2A battery charger output, with 160W total output power. That makes it a fit for 24V-class control, automation, or panel backup applications that use a 27.6V charging profile and need UPS function support.

Is the PSC-160B-C suitable for telecom or IT backup equipment that runs on 24V-class DC battery systems?

This model provides 27.6V with a 3.8A rated load current from a 90-264VAC input range, so it matches 24V-class battery-backed equipment that expects that charging voltage. Its UPS function also makes it relevant for standby power roles in IT or communications cabinets.

Can the PSC-160B-C be used in embedded or automation systems with higher DC load demand than smaller PSC models?

Yes, within its rating: 160W total at 27.6V, with 3.8A rated on the load output (current range 0-5.8A) plus a 2A battery charger output. This datasheet covers only the PSC-160 models, so compare smaller PSC models against their own datasheets before choosing.

Is the PSC-160B-C intended for indoor or outdoor environments?

The provided specs list an operating temperature range of -20°C to +70°C, but they do not list an IP rating. Without an IP rating in the product specs, outdoor exposure should not be assumed from this data alone.

How does the PSC-160B-C compare with other PSC 27.6V models?

The PSC-160B-C is the enclosed version (L-bracket and cover, 155.4x85x37mm) of the PCB-type PSC-160B (152.4x76.2x32mm). Both deliver 27.6V at 160W, rated 3.8A for the load plus 2A for battery charging, with 90% efficiency; the enclosed type follows its own derating curve. Smaller PSC models are not covered by this datasheet.
