FAQs
The TRH70A is available in output voltages from 12Vdc through to 48Vdc at 70W continuous output — the same voltage range as the TRH50A and TRH100A series. Output current is proportionally higher than the TRH50A at each voltage (e.g. approximately 5.83A at 12Vdc at 70W). Contact Powerbox at sales@powerbox.com.au to confirm the specific model for your required output voltage.
The TRH70A carries the RCM (Regulatory Compliance Mark) to AS/NZS 4417 and Certificate of Approval ESO160362, confirming compliance with Australian and New Zealand electrical safety requirements under AS/NZS 62368.1:2022. CE and RoHS compliance applies for international market use.
It meets DoE Level VI and CoC V5 Tier 2 under the GEMS Determination 2014 (External Power Supplies High Efficiency 2014 Mark VI), with no-load power consumption below 150mW — the same efficiency standard as the TRH50A and TRH100A, making the full TRH series compliant with Australian energy efficiency regulations for external power supplies.
Operating temperature is -20°C to +70°C with natural convection cooling — identical to the TRH50A. The TRH100A extends the lower limit to -30°C if cold-temperature operation is a priority.
Safety: IEC/EN/UL 62368-1 (Class I, with PE connection required). EMC: EN55022 Class B and CISPR/FCC Class B for conducted and radiated emissions, with EN61000-3-2 harmonic current compliance. Input-to-output isolation is 4,242Vdc.
Choose the TRH70A when the continuous load power falls between 50W and 70W — it provides additional current headroom over the TRH50A without the larger size and active PFC of the TRH100A. All three are appropriate for industrial, IT, and telecommunications desktop power applications. An IEC mains cable (Cincon IEC Cable or Powerbox PBB3S-Series) must be ordered separately. Contact Powerbox at sales@powerbox.com.au.
